    Appeal from the United States District Court

    ________________________
    (May 29, 2015)
    Before HULL, ROSENBAUM and FAY, Circuit Judges.
    PER CURIAM:
    Case: 14-13895        Date Filed: 05/29/2015   Page: 2 of 25
    Paul H. Ostborg, Jr., appeals the district judge’s final order affirming denial
    of his application for disability and disability-insurance benefits under 42 U.S.C.
    § 405(g) by the Social Security Administration (“SSA”). We affirm.
    I.      BACKGROUND
    Ostborg, a United States military veteran, has suffered from scoliosis, flat
    feet, and a leg-length discrepancy for most of his life. In August 1996, Ostborg
    filed his first application seeking disability-insurance benefits under Title II and
    Part A of Title XVIII of the Social Security Act and represented his disability
    began on August 5, 1996. In December 1996, Ostborg suffered a head injury,
    when he slipped on ice and fell. On June 25, 1998, an administrative law judge
    (“ALJ”) denied his first application (“the 1998 Decision”). Ostborg filed his
    second and subject application for disability benefits on September 24, 2004. He
    last met the insurance requirements on December 31, 2001.
    A.    Medical Evidence
    1.     Mental-Health Records
    Dr. Fredric Rose, a neuropsychologist, evaluated Ostborg on January 15,
    1998. Ostborg complained he had experienced several impairments since his 1996
    accident, including periods of confusion, impaired short-term memory, fatigue,
    forgetting details, although he reported good recognition if cued, and language
    errors, when stressed or fatigued. While Ostborg was able to perform the activities
    2
    Case: 14-13895   Date Filed: 05/29/2015   Page: 3 of 25
    of daily life since his accident, it took effort, and he could no longer accomplish as
    much each day. Ostborg was a musician; he reported no difficulty with the
    cognitive aspects of playing music since his accident.
    After testing Ostborg, Dr. Rose concluded he showed slowed-information-
    processing speed and difficulty processing information on the first exposure, but
    substantial improvement in recall and retention after subsequent exposures. He
    opined Ostborg needed extended time and repetition to process new material, but
    Ostborg could complete basic and complex tasks, if given sufficient time and
    structure.
    Nearly eight months after Dr. Rose’s evaluation, Ostborg asked if he was
    “willing to write a note saying [he] can’t work.” R. at 319. Dr. Rose wrote the
    requested letter, but instead of stating Ostborg could not work, he summarized his
    findings concerning Ostborg’s limitations as follows:
    Day to day functioning, therefore, may be affected in part
    by this difficulty in processing and encoding even
    “automatic” events such as preparing to go out for the
    day. Extra time to plan and organize what must be done
    is now more of a necessity than in the past. Given
    sufficient time and structure, however, there was no
    evidence from this evaluation that you would be unable
    to complete basic or even complex tasks. Cognition and
    intelligence were otherwise sufficiently intact to allow
    the performance of most, if not all, tasks previously
    completed, though at a slowed pace requiring additional
    structure and time.
    R. at 318-19.

    Case: 14-13895     Date Filed: 05/29/2015   Page: 4 of 25
    On January 21 and February 2, 1998, Ostborg additionally was evaluated by
    Dr. John Stuart Currie, also a neuropsychologist. Ostborg complained to Dr.
    Currie of short-term-memory problems, lack of concentration, and becoming
    fatigued quickly. Ostborg completed an IQ test and performed below expectations,
    considering his education. But Dr. Currie attributed this to factors other than a
    natural deficit, including Ostborg’s taking Vicodin. Dr. Currie also noted Ostborg
    showed confidence in driving, homemaking, exercising, and musical performance.
    Ostborg’s next mental-health treatment occurred after December 31, 2001,
    the last date he was insured. He obtained psychological and psychiatric treatment
    in October 2002, as well as in 2005, 2009 and 2010. Records of these later
    treatments discuss his history with his impaired memory, concentration, and
    information-processing speed.
    2.    Physical-Health Records
    In July 1997, Ostborg’s primary-care physician, Dr. Charles Demosthenes,
    noted Ostborg’s scoliosis had worsened and caused him severe pain.
    Dr. Demosthenes also discussed Ostborg’s leg-length discrepancy and explained
    other doctors’ reports of the extent of the discrepancy had varied. In September
    1997, Dr. Demosthenes referred Ostborg for corrective shoes.
    In an October 2001 annual examination, Ostborg reported chronic pain of an
    unspecified degree in his neck, back, and extremities. He also reported some
    4
    Case: 14-13895    Date Filed: 05/29/2015   Page: 5 of 25
    musculoskeletal pain, but it was controlled with chiropractic treatments and
    swimming. He complained of two skin lesions and tightness on his left side after
    swimming. According to a July 2004 treatment note, Ostborg stated he never
    drank alcohol. In a June 2005 psychiatric general progress note, however, Ostborg
    reported he had stopped abusing alcohol in 1969, after being discharged from the
    military.
    Ostborg has received regular chiropractic treatment from 1990; records from
    that treatment generally indicate he suffers from lower back pain, neck spasms, and
    stiff, restricted joint movement. In August 2000, chiropractor Richard Franks
    wrote a letter in support of Ostborg’s claim for disability benefits from the
    Veteran’s Administration (“VA”) and explained corrective shoes helped to
    compensate for Ostborg’s leg-length discrepancy.
    B.    Work History
    From 1975 through 1994, Ostborg worked for up to 32 hours per week as a
    house manager at Grady Memorial Hospital. He assisted in the relocation of
    students and interns, helped assure smooth operation of house management,
    monitored security, and sometimes typed letters. Ostborg sat for approximately six
    to eight hours per day; he had to walk, stand, and climb stairs occasionally; he did
    not lift anything weighing more than ten pounds.
    5
    Case: 14-13895     Date Filed: 05/29/2015   Page: 6 of 25
    From 1994 through 1996, Ostborg worked as a security guard. He
    maintained basic order and safety of the premises and wrote some reports. He sat
    most of the time, walked and climbed stairs occasionally; he never lifted anything
    in excess of ten pounds. He also had to undergo first-aid and CPR training for that
    position. Neither of these jobs required technical knowledge; he did not supervise,
    hire, or fire employees in either position.
    C.    1998 ALJ Decision
    The 1998 ALJ Decision states Ostborg had represented he was disabled
    because of scoliosis, pes planus (flat feet), and leg-length discrepancy in his
    previous application for disability benefits. He also had testified about the limiting
    effects of his December 1996 fall. The ALJ concluded Ostborg’s testimony
    concerning his impairments was incredible in view of the medical evidence and his
    description of his activities and lifestyle. The ALJ also discussed various medical
    records, including Dr. Currie’s evaluation, which identified no significant memory
    or cognitive dysfunctions. The ALJ concluded Ostborg had no more than minimal-
    mental impairments to work-related functioning, and he retained the residual
    functional capacity (“RFC”) to perform medium work.
    6
    Case: 14-13895        Date Filed: 05/29/2015        Page: 7 of 25
    D.     VA Disability Determination
    On January 16, 1999, the VA determined Ostborg was disabled. 1 The VA
    decision lists Ostborg’s disabilities as degenerative-disc disease of the cervical and
    lumbar spines, dextroscoliosis of the lumbar spine, degenerative changes of the
    thoracic spine, residuals from a head injury, and leg-length discrepancy.
    Medical findings of various doctors are summarized in the decision,
    including the opinion of Dr. Lee Jacobs that Ostborg could work a desk job for not
    more than four hours a day. The rating decision also briefly summarized a
    December 21, 1996, report from Cobb Hospital and Medical Center concerning
    Ostborg’s accident and stated Ostborg had suffered trauma to the back of his head.
    The VA determined Ostborg did not meet the schedular-requirements
    disability. 2 The VA rated his disabilities as (1) 20% for degenerative-disc disease
    of the lumbar spine with dextroscoliosis, (2) 10% for his leg-length discrepancy,
    (3) 10% for degenerative-disc disease and osteoarthritis of the cervical spine,
    (4) 10% for degenerative changes of the thoracic spine, and (5) 10% for residuals
    from a concussion. Nevertheless, the VA determined that “an extraschedular
    permanent and total disability rating [was] authorized,” based on Ostborg’s “level
    1
    The rating decision in the record is undated; however, the exhibit list states the decision
    was issued on January 16, 1999. Additionally, a duplicate-partial copy of the VA rating decision
    has the same date handwritten on one of the pages.
    2
    The schedular requirements are (1) a single disability ratable at 60% or more, or
    (2) two or more disabilities combining to 70% with at least one ratable at 40%.
    7

    of disability and other factors, such as [his] age, education and occupational
    background.” R. at 192.
    E.    2008 ALJ Decision and Remand by the Appeals Council
    1.     2008 Hearing
    On May 28, 2008, at a hearing concerning Ostborg’s subject application for
    disability benefits, Ostborg testified that, as a security guard, he sometimes worked
    full-time and sometimes part-time, depending on what was available and what he
    could handle. He characterized his job as a house manager as a “desk job” that
    involved admitting people to the residence halls.
    Ostborg testified his grip was fair. He experienced difficulty walking,
    bending over, climbing stairs, and lifting anything over ten pounds. He became
    fatigued frequently and needed to lie down several times per day. He had
    experienced some improvement in his memory in the seven years following his
    1996 fall, but none thereafter.
    Immediately following Ostborg’s 1996 fall, he was in a great deal of pain;
    he could not drive and had difficulty concentrating. In the past three years,
    however, he had driven from Atlanta, Georgia, to Asheville, North Carolina, to
    visit his sister. Ostborg lived alone, shopped for himself, and attended church. He
    also exercised regularly, by swimming two to three times a week for about 30
    minutes, doing aerobics, and walking. At one time, Ostborg had freelanced as a
    8
    Case: 14-13895     Date Filed: 05/29/2015   Page: 9 of 25
    violin player, but he could no longer play well because of arthrosis, a degenerative-
    joint disease, in his hands.
    Ostborg had volunteered at his church periodically for the past year and a
    half by sitting at the front desk for about 45 minutes to greet people and make sure
    they knew where they were going. For the past three years, he has volunteered at a
    museum in Smyrna, Georgia once per week, which also involved greeting people,
    asking them to sign in, and showing them around. Asked why he could not
    perform his previous job in security in view of his exercise and volunteer activities,
    Ostborg responded he volunteered only on a limited basis; his other activities were
    low stress and did not require him to be on his feet or to remember anything.
    The following exchange occurred between the ALJ and Ostborg:
    ALJ:          I mean it’s kind of hard to imagine that you
    don’t have to concentrate at the museum job
    and the church job. I mean you kind of
    know a lot of stuff and where to send
    people, and you have to know your way
    around.
    ....
    Wouldn’t that be similar to what you had to
    do at the hospital [or] when you were doing
    the security work?
    OSTBORG: Well, in a way, but at the hospital I had a lot
    more to deal with. A lot more people to, a
    lot more people coming in, just a lot more to
    do.

    .
    2.     2008 ALJ Decision and Remand by the Appeals Council
    In September 2008, the ALJ issued a decision denying Ostborg’s claim for
    disability benefits. The ALJ mentioned Ostborg had sought and been awarded
    disability benefits by the VA but did not discuss further the VA’s disability rating.
    Additionally, the ALJ found Ostborg’s testimony concerning his limitations to be
    incredible because, in the hearing, he described only minimal volunteer work, but a
    Google search of Ostborg revealed a much wider array of activities.
    Ostborg sought review from the Appeals Council (“AC”). The AC
    remanded the case to the ALJ. The AC concluded the ALJ had failed to provide
    Ostborg with the post-hearing evidence obtained from the internet and to discuss
    adequately the VA’s disability rating or indicate the weight that the VA’s
    determination was accorded.
    F.    Post-Remand Proceedings
    1.     2010 Hearing
    At a hearing in November 2010, the ALJ provided Ostborg and his counsel
    with printouts from the ALJ’s Google search; Ostborg provided additional
    testimony concerning his hobbies and volunteer activities. In August 2008,
    following the 2008 hearing, but before the ALJ’s 2008 decision, Ostborg had
    presented two sessions on veterans benefits at Life University, which involved
    10
    Case: 14-13895     Date Filed: 05/29/2015   Page: 11 of 25
    standing and teaching for approximately an hour each time. Ostborg’s original art
    work was displayed at an exhibition at the Smyrna Library Gallery for about two
    months. Approximately 8 to 10 drawings and paintings, which Ostborg had
    produced over the past forty years, were on display. While Ostborg did not need to
    be present during the exhibition, he went approximately once a week to check in.
    Ostborg further testified he had taken numerous pictures of houses and
    properties for the Smyrna Historical and Genealogical Society (“SHGS”) in 2006.
    He did so approximately once a month for three years. Additionally, Ostborg
    volunteered at the SHGS museum three Saturdays per month, which involved
    remaining at a desk, assisting people as needed, and answering questions. He was
    a member of the Cobb County Stamp Club. He attended meetings, which occurred
    twice a month, and volunteered at shows periodically.
    Ostborg had given violin and viola instruction privately in the past, but he
    had not done so for at least the past five years. When he last taught violin, Ostborg
    had one student, with whom he met once a week for approximately one year.
    Although Ostborg was listed on the roster of private violin instructors for a middle
    school in Georgia, he did not know how his name came to be on that list. Ostborg
    was asked again why he could not have used his mind to work instead of to
    volunteer; Ostborg responded he volunteered only occasionally, and he could
    pursue his volunteer and other activities as he was inclined.
    11
    Case: 14-13895       Date Filed: 05/29/2015       Page: 12 of 25
    2.      2011 ALJ Decision and Request for Review
    Although Ostborg represented his disability began on August 5, 1996, the
    ALJ concluded the June 25, 1998, denial of his previous application had the effect
    of administrative res judicata. Consequently, the relevant period began on June 26,
    1998. The ALJ followed the five-step sequential process in evaluating Ostborg’s
    disability claim. 3 At step two, the ALJ found Ostborg had the severe impairments
    of scoliosis, leg-length discrepancy, and residuals from a 1996 closed-head injury.
    In evaluating the effects from Ostborg’s 1996 fall and head injury, the ALJ
    discussed Dr. Rose’s findings and letter at length. In the analysis at step three, the
    ALJ acknowledged Ostborg had exhibited deficits on medical examinations with
    regard to concentration, persistence, or pace, but found he was only mildly
    impaired, because he was able to drive long distances and navigate to new areas
    successfully. At step four, the ALJ found Ostborg capable of performing only light
    work, because of his leg-length discrepancy. Because of his lapses in
    concentration, the ALJ also determined he could work up to 32 hours per week.
    3
    Under the five-step sequential process to determine whether a claimant is disabled, the
    claimant must show (1) he is not currently engaged in substantial gainful activity; (2) he has a
    severe impairment; (3) his impairment meets or equals the criteria in one of the listed
    impairments in 20 C.F.R. Part 404, Subpart P, Appendix 1; and (4) his impairment prevents him
    from performing his past relevant work. 20 C.F.R. § 404.1520(a)(4)(i)-(iv). If the claimant
    shows he cannot perform his past relevant work, then, at the fifth step, the burden shifts to the
    Commissioner to show significant numbers of jobs exist in the national economy the claimant
    can perform. 
    Id. § 404.1520(a)(4)(v).
                                                   12
    Case: 14-13895     Date Filed: 05/29/2015    Page: 13 of 25
    The ALJ found Ostborg’s medically determinable impairments could
    reasonably be expected to produce his alleged symptoms but decided his testimony
    regarding the intensity, persistence, and limiting effects of those symptoms to be
    incredible. The ALJ explained Ostborg was engaged in a far wider variety of
    hobbies and activities than he originally had represented. While these hobbies and
    activities did not directly contradict his allegations of disability, the ALJ found
    they were sufficiently inconsistent with his stated mental limitations and did not
    support his overall credibility. The ALJ noted various inconsistent statements
    Ostborg had made elsewhere in the record, including the discrepancy in his
    statements to his doctors concerning his alcohol consumption. Additionally, the
    ALJ highlighted Ostborg’s testimony he could not direct his energies toward work,
    in view of his volunteer and other activities, because he volunteered only randomly
    and pursued his hobbies, when he was so inclined. The ALJ also found the VA’s
    disability determination had “little bearing” on Ostborg’s claim for Social Security
    disability benefits, because the VA used a different standard to assess disability
    and may not have been aware of his hobbies and activities. R. at 41.
    Ostborg again requested AC review of the ALJ’s decision. This time, the
    AC denied review and adopted the ALJ’s decision as the final decision of the
    Commissioner. Through counsel, Ostborg has appealed that decision to this court.

    II.    DISCUSSION
    As an initial matter, the government states the relevant time period of
    disability for Ostborg’s case began on June 26, 1998, because the 1998 Decision
    had the effect of administrative res judicata. Ostborg does not discuss this issue in
    his initial brief. In his reply brief, he asserts (1) the ALJ actually considered the
    relevant period to have begun on August 28, 1996, despite the purported
    application of administrative res judicata; and (2) the application of administrative
    res judicata is immaterial to his arguments on appeal.
    “[T]he law is by now well settled in this Circuit that a legal claim or
    argument that has not been briefed before the court is deemed abandoned and its
    merits will not be addressed.” Access Now, Inc. v. Sw. Airlines Co., 
    385 F.3d 1324
    , 1330 (11th Cir. 2004). Abandonment can occur when an appellant makes
    only passing reference to the claim. Sapuppo v. Allstate Floridian Ins. Co., 
    739 F.3d 678
    , 681-82 (11th Cir. 2014). Moreover, we will not address arguments made
    for the first time in a reply brief. 
    Id. at 682-83.
    Because Ostborg did not raise the issue of administrative res judicata in his
    initial brief, he has abandoned it. Access Now, 
    Inc., 385 F.3d at 1330
    . His mention
    of the issue in his reply brief is both belated and insufficient to raise an argument
    of error, because (1) he first raises it in his reply brief, and (2) in the two sentences
    where he discusses the issue, he maintains the application of res judicata was
    14
    Case: 14-13895     Date Filed: 05/29/2015   Page: 15 of 25
    immaterial or the ALJ did not actually apply it, not that the ALJ erred in applying
    it. 
    Sapuppo, 739 F.3d at 681-83
    . Accordingly, we deem this issue abandoned.
    Our subsequent discussion clarifies Ostborg has not shown reversal is warranted,
    even if the ALJ implicitly determined he was not disabled prior to June 26, 1998.
    A.           ALJ Gave Sufficient Weight to VA’s Rating Decision
    Ostborg argues the ALJ failed to accord the VA’s rating decision sufficient
    weight and provided an inadequate explanation for the determination the VA’s
    decision had little bearing on Ostborg’s claim for Social Security disability
    insurance benefits. He also argues the ALJ discussed the medical evidence that
    was provided in support of and summarized in the VA’s decision.
    We review the ALJ’s decision for substantial evidence but his application of
    legal principles de novo. Moore v. Barnhart, 
    405 F.3d 1208
    , 1211 (11th Cir.
    2005). The SSA regulations provide a decision by any nongovernmental or
    governmental agency concerning whether an individual is disabled, based on that
    agency’s own rules, does not constitute an SSA decision regarding whether that
    individual is disabled. 20 C.F.R. § 404.1504. A VA rating, while not binding on
    the SSA, “is evidence that should be considered and is entitled to great weight.”
    Brady v. Heckler, 
    724 F.2d 914
    , 921 (11th Cir. 1984) (internal quotation marks
    omitted); see also Rodriguez v. Schweiker, 
    640 F.2d 682
    , 686 (5th Cir. Unit A Mar.
    1981).
    15
    Case: 14-13895    Date Filed: 05/29/2015    Page: 16 of 25
    For Social Security purposes, a claimant is entitled to disability insurance
    benefits, when he proves he is under a disability, meaning he is unable “to engage
    in any substantial gainful activity by reason of any medically determinable
    physical or mental impairment.” 42 U.S.C. § 423(a)(1)(E), (d)(1)(A). In contrast,
    the VA generally will grant total disability, when “there is present any impairment
    of mind or body which is sufficient to render it impossible for the average person
    to follow a substantially gainful occupation.” 38 C.F.R. § 3.340(a)(1).
    Additionally, the VA “shall give the benefit of the doubt to the claimant,”
    whenever “there is an approximate balance of positive and negative evidence
    regarding any issue material to the determination of a matter.” 38 U.S.C. § 5107.
    In Brady, the claimant received a 100% disability rating from the VA, but
    the ALJ concluded the claimant did not have a severe impairment. 
    Brady, 724 F.2d at 917
    . Based on the medical evidence, we concluded the claimant had a
    severe impairment and remanded for the ALJ to consider whether his impairments
    precluded him from performing his past work. 
    Id. at 921.
    In Rodriguez, we
    concluded the ALJ should have “more closely scrutinized” the VA’s disability
    rating of 100% for the claimant, where the ALJ mentioned the rating but
    “obviously refused to give it much weight.” 
    Rodriguez, 640 F.2d at 686
    .
    The record in this case shows the ALJ closely scrutinized the VA’s disability
    decision and gave specific reasons for determining the VA’s determination had
    16
    Case: 14-13895     Date Filed: 05/29/2015     Page: 17 of 25
    little bearing on Ostborg’s case. See 
    Brady, 724 F.2d at 917
    ; 
    Rodriguez, 640 F.2d at 686
    . Substantial evidence supports the ALJ’s reasons for discounting the VA’s
    determination, because that determination makes no mention of Ostborg’s
    wide-ranging hobbies and interests. In addition, the ALJ correctly explained the
    VA and SSA use different criteria for determining disability. Compare 38 C.F.R.
    § 3.340(a)(1), with 42 U.S.C. § 423(a)(1)(E), (d)(1)(A).
    Notably, this case is distinguishable from Brady and Rodriguez. In contrast
    to Brady, the ALJ determined Ostborg suffered from severe impairments. See
    
    Brady, 724 F.2d at 917
    . Moreover, in contrast to the claimants in Brady and
    Rodriguez, Ostborg was not given a 100% disability rating from the VA; instead,
    his maladies fell short of meeting the VA’s schedular requirements for disability,
    but he was given a permanent and total disability rating based on extraschedular
    factors. See id. ; 
    Rodriguez, 640 F.2d at 686
    . Moreover, the VA’s rating decision
    in Ostborg’s case, provides scant explanation for applying those extraschedular
    factors to reach a determination of total disability, when the schedular factors do
    not meet the VA’s disability criteria.
    Ostborg’s argument the ALJ failed to acknowledge medical records
    provided in support of the VA’s decision is meritless. Much of the medical
    evidence summarized in the VA’s decision was not in the record before the ALJ in
    this case. The ALJ’s specific reasons for discounting the VA’s determination show
    17
    Case: 14-13895     Date Filed: 05/29/2015    Page: 18 of 25
    he considered and closely scrutinized that determination; consequently, the ALJ
    did not misapply the law in discounting it. See 
    Moore, 405 F.3d at 1211
    ;
    
    Rodriguez, 640 F.2d at 686
    .
    B.    Substantial Evidence Supporting ALJ’s Work Finding
    Ostborg argues the ALJ’s RFC finding is unsupported by substantial
    evidence, because the finding conflicts with medical evidence underlying the VA’s
    disability rating. He also contends the ALJ failed to discuss the reasons for
    disregarding Dr. Rose’s opinion concerning his concentration and pace limitations
    or the limitations created by his leg-length discrepancy. Finally, Ostborg contends
    he was unable to perform his previous jobs. Regarding his security-guard job, he
    argues the Dictionary of Occupational Titles provides security-guard work
    involves responding quickly to unexpected circumstances.
    We review the ALJ’s decision for substantial evidence. 
    Moore, 405 F.3d at 1211
    . “Substantial evidence is less than a preponderance, but rather such relevant
    evidence as a reasonable person would accept as adequate to support a
    conclusion.” 
    Id. The Social
    Security Regulations state a five-step process used to
    determine whether a claimant is disabled. See 20 C.F.R. § 404.1520(a)(4). Under
    the first four steps of that process, the claimant must show: (1) he is not currently
    engaged in substantial gainful activity; (2) he has a severe impairment; (3) his
    impairment meets or equals the criteria in one of the listings of impairments; and
    (4) his impairment prevents him from performing past relevant work, if it does not
    18
    Case: 14-13895     Date Filed: 05/29/2015   Page: 19 of 25
    meet or equal one of the impairments in the listings. 
    Id. § 404.1520(a)(4)(i)-(iv).
    If the claimant shows he cannot perform his past relevant work, then, at the fifth
    step, the burden shifts to the Commissioner to show significant numbers of jobs
    exist in the national economy the claimant can perform. 
    Id. § 404.1520(a)(4)(v).
    At step four, the ALJ assesses the claimant’s RFC and ability to perform
    past relevant work. 
    Id. § 404.1520(a)(4)(iv).
    The RFC assessment is based on all
    relevant evidence of a claimant’s abilities to do work despite his impairments.
    Lewis v. Callahan, 
    125 F.3d 1436
    , 1440 (11th Cir. 1997) (citing 20 C.F.R.
    § 404.1545(a)). “Light work” is defined as work involving “lifting no more than
    20 pounds at a time with frequent lifting or carrying of objects weighing up to 10
    pounds.” 
    Id. § 404.1567(b).
    A job in the light-work category may require “a good
    deal of walking or standing, or . . . sitting most of the time with some pushing and
    pulling of arm or leg controls.” 
    Id. The claimant
    bears the burden of showing he cannot perform his past
    relevant work. Lucas v. Sullivan, 
    918 F.2d 1567
    , 1571 (11th Cir. 1990). A
    claimant must show he is unable to perform his past kind of work, not merely that
    he is unable to perform a specific job held in the past. Jackson v. Bowen, 
    801 F.2d 1291
    , 1293 (11th Cir. 1986) (citing 20 C.F.R. § 404.1520(e)). At the fourth step,
    the ALJ assesses the claimant’s RFC. Phillips v. Barnhart, 
    357 F.3d 1232
    , 1237
    (11th Cir. 2004). “[T]he regulations define RFC as that which the individual is
    19
    Case: 14-13895     Date Filed: 05/29/2015    Page: 20 of 25
    still able to do despite the limitations caused by his or her impairments.” 
    Id. (citing 20
    C.F.R. § 404.1545(a)). The ALJ makes the RFC determination based on all
    relevant medical and other evidence in the case. 
    Id. 1. ALJ’s
    RFC Assessment
    Substantial evidence supports the ALJ’s determination Ostborg could
    perform light work for 32 hours per week, despite his leg-length discrepancy. See
    
    Moore, 405 F.3d at 1211
    . Ostborg obtained corrective shoes, which according to
    his chiropractor, helped to compensate for his leg-length discrepancy.
    Additionally, Ostborg testified he frequently walked and swam. Consequently,
    substantial evidence supports the ALJ’s finding that Ostborg could perform light
    work. See 
    id. Contrary to
    Ostborg’s contention, the ALJ gave sufficient reasons for the
    determination his leg-length discrepancy limited him to light work. The ALJ
    described Ostborg’s leg-length discrepancy in detail at step two of the analysis,
    including the treatment he had obtained. The ALJ also found, at step three,
    Ostborg was able to function normally, evidenced by his exercising regularly.
    Moreover, substantial evidence supports this conclusion because Ostborg’s
    October 2001 treatment notes show his musculoskeletal pain was well controlled
    with chiropractic treatment and regular swimming, his chiropractor opined
    Ostborg’s corrective shoes helped compensate for his leg-length discrepancy, and
    20
    Case: 14-13895     Date Filed: 05/29/2015    Page: 21 of 25
    Ostborg testified he walked, swam, and did aerobics regularly. See 
    Moore, 405 F.3d at 1211
    .
    The medical reports and RFC assessments in the record support the ALJ’s
    conclusion Ostborg was able to work on a part-time basis, despite any pace
    limitations. For instance, Dr. Rose opined (1) Ostborg was capable of performing
    most, if not all, tasks that he was previously able to perform, despite needing extra
    time and structure; (2) he could perform complex tasks with sufficient time and
    structure; and (3) his cognition and intelligence were otherwise sufficiently intact.
    The ALJ discussed Dr. Rose’s report and concluded Ostborg’s cognitive
    limitations were mild, and Dr. Rose’s assessment does not contradict that
    conclusion. Moreover, the ALJ explicitly accounted for Ostborg’s lapses in
    concentration and inability to sustain sufficient concentration for a 40-hour work
    week. Ostborg’s argument the ALJ’s RFC decision is unsupported by substantial
    evidence, because it conflicts with the evidence underlying the VA’s decision is
    meritless. The evidence underlying the VA’s decision to which Ostborg refers, Dr.
    Jacobs’s opinion Ostborg could perform only sedentary work for four hours a day,
    was not in the record. Instead, the record contained only the brief summary of that
    evidence, which was recited in the VA’s decision.
    21
    Case: 14-13895    Date Filed: 05/29/2015   Page: 22 of 25
    2.    Ostborg’s Ability to Perform his Past Relevant Work
    Ostborg does not dispute his previous jobs as a house manager and in
    security services were past-relevant work for purposes of the Social Security
    regulations. Ostborg’s prior jobs involved mostly sitting, only occasional lifting
    objects less than ten pounds, some typing, and did not include supervising others.
    Nothing in the record shows these tasks were beyond his RFC. He described his
    house-manager job as a desk job and acknowledged it was somewhat similar to his
    volunteer roles at the church and museum. Ostborg’s testimony his work as a
    house manager involved “a lot more people” and “a lot more to do” than his
    volunteer roles, does not show that such a role was beyond his abilities, because it
    is not clear that admitting more people would tax his abilities to process new
    information. Instead, Ostborg described a greater frequency of the same task, and
    Ostborg has not shown he had difficulties repeating tasks. See 
    Lucas, 918 F.2d at 1571
    .
    Because Ostborg previously has not raised his argument concerning the
    nature of security-guard work as described in the Dictionary of Occupational
    Titles, we need not address it. See Kelley v. Apfel, 
    185 F.3d 1211
    , 1215 (11th Cir.
    1999) (declining to reach an argument not raised before the SSA or the district
    court that the ALJ should have relied on a VE’s testimony). Ostborg has not met
    22
    Case: 14-13895     Date Filed: 05/29/2015     Page: 23 of 25
    his burden of showing he could not perform his past relevant work. See 
    Lucas, 918 F.2d at 1571
    .
    C.    ALJ’s Credibility Determination
    Ostborg contends the ALJ identified only minor discrepancies in his various
    statements, such as his allegedly inconsistent statements concerning alcohol
    consumption. He contends these discrepancies and his wide range of hobbies and
    activities were insufficient to contradict his allegations of disability.
    Credibility determinations are the province of the ALJ, and we will not
    disturb a clearly articulated credibility finding absent substantial evidence.
    Mitchell v. Comm’r, Soc. Sec. Admin., 
    771 F.3d 780
    , 782 (11th Cir. 2014). When a
    claimant attempts to show disability through his own testimony about pain or other
    subjective symptoms, the ALJ must consider that testimony if the ALJ finds
    evidence of an underlying medical condition and either (1) objective medical
    evidence to confirm the severity of the alleged symptoms arising from that
    condition, or (2) the objectively determined medical condition is of a severity that
    reasonably can be expected to give rise to the alleged symptoms. See Foote v.
    Chater, 
    67 F.3d 1553
    , 1560 (11th Cir. 1995). If the claimant establishes an
    underlying medical condition that reasonably could be expected to produce the
    symptoms, “all evidence about the intensity, persistence, and functionally limiting
    effects of pain or other symptoms must be considered in addition to the medical
    23
    Case: 14-13895     Date Filed: 05/29/2015    Page: 24 of 25
    signs and laboratory findings in deciding the issue of disability.” 
    Id. at 1561.
    If
    the ALJ decides not to credit a claimant’s testimony regarding his subjective
    symptoms, the ALJ must articulate “explicit and adequate reasons for doing so.”
    
    Id. at 1561-62.
    The ALJ may consider a claimant’s daily activities in discrediting
    complaints concerning subjective conditions. See Harwell v. Heckler, 
    735 F.2d 1292
    , 1293 (11th Cir. 1984) (concluding the ALJ properly considered a variety of
    factors, including the claimant’s daily activities, in making a finding about his
    allegations of severe pain).
    In this case, the ALJ discussed Ostborg’s mental limitations earlier in his
    decision and found them to be mild based on the objective medical evidence. In
    discussing Ostborg’s credibility, the ALJ stated several specific reasons for
    discounting Ostborg’s statements concerning his symptoms, and substantial
    evidence supports those reasons. 
    Foote, 67 F.3d at 1561-62
    . Specifically, the ALJ
    found Ostborg was engaged in a wider array of activities than he originally had
    represented. Substantial evidence supports this determination, because Ostborg
    had failed to testify about his violin instruction, photography, art exhibition, and
    involvement in the stamp club. Moreover, the ALJ’s consideration of Ostborg’s
    wide range of activities was proper, because (1) Ostborg alleged he was unable to
    work, in part, because of his mental impairments, but (2) his wide ranging
    activities included activities the ALJ found to be similar or more mentally
    24
    Case: 14-13895     Date Filed: 05/29/2015    Page: 25 of 25
    challenging than his previous jobs. See 
    Harwell, 735 F.2d at 1293
    . The ALJ’s
    discussion of other inconsistent statements, such as those concerning Ostborg’s
    alcohol consumption, even if erroneous, was harmless, since substantial evidence
    supports the ALJ’s credibility finding. See 
    Mitchell, 771 F.3d at 782
    ; Diorio v.
    Walker, 
    721 F.2d 726
    728 (11th Cir. 1983) (concluding the ALJ’s
    mischaracterization of the claimant’s post-relevant work was harmless error,
    because such characterization of vocational factors was irrelevant when the ALJ
    found no severe impairment). The ALJ’s credibility determination is supported by
    substantial evidence. See 
    Mitchell, 771 F.3d at 782
    .
    III.   CONCLUSION
    In summary, the ALJ did not misapply the law in determining the VA’s
    disability rating had little bearing on Ostborg’s disability benefits claim. In
    addition, substantial evidence supported the ALJ’s findings (1) Ostborg possessed
    the RFC to perform light work on a part-time basis and his past relevant work; and
    (2) his testimony concerning the persistence, severity, and limiting effects of his
    impairments was not credible.
    AFFIRMED.
