Jerome F. Naber seeks social security disability insurance benefits. An administrative law judge (ALJ) found that Naber became disabled on January 5, 1991, and awarded him benefits from that date forward. Naber filed this action to challenge the ALJ’s decision, arguing that he also should receive benefits for the period from November 1, 1989, to January 4, 1991. The district court 1 entered judgment for the Secretary. Naber appеals, and we affirm.
I.
Naber was born January 5, 1936. He has a high school education. He was employed for thirteen years as a manager of a farm supply cooperative, for nine years as a construction crew foreman, and for eight years as a seasonal farmworker driving farm equipment. He has not been gainfully employed since October 1989, when he drove a combine and а tractor for a neighboring farmer. Na-ber’s application for benefits claimed that he has been disabled since November 1, 1989, because of arthritis, neck pain, and a painful condition in his right еye.
After an evidentiary hearing, an ALJ evaluated Naber’s claim according to the familiar five-step analysis prescribed by Social Security Administration regulations.
See
20 C.F.R. § 404.1520;
Bowen v. Yuckert,
II.
The ultimate issue in this appeal is whether Naber was disabled from November 1, 1989, to January 4, 1991, a period of aрproximately 14 months. “The findings of the Secretary as to any fact, if supported by substantial evidence, shall be conclusive....” 42 U.S.C. § 405(g). We do not reweigh the evidence or review the factual recоrd de novo.
See Loving v. Shalala,
Naber first contends that the ALJ did not properly consider his subjective complaints of pain when he considered Naber’s residual functional capacity. The ALJ must give full consideration to all evidence relevant to a claimant’s subjective complaints of pain. The ALJ “is not free to accept or reject the claimant’s subjective complaints
solely
on the basis of personal observations. Subjective comрlaints may be discounted if there are inconsistencies in the evidence as a whole.”
Polaski v. Heckler,
Naber testified that he experienced considerable pain in his shoulder, arm, and neck in the fall of 1989. (Tr. at 34.) Naber submitted an affidavit of his then-employer to corroborate his complaints of pain. 2 At the conclusion of the evidentiary hearing, Naber also testified as follows:
Q. What are you going to do now in the future? What are your plans for the future? Let's assume that you do, that you are awarded Disability Benefits. Then what are you going to do with the rest of your life?
A. I don’t know, I’ve thought about that. My original intention is to go back to Miller, South Dakota, my home town, and I’ll probably stay with my mother a short period of time. My brother has a big ranch, farm up there, I might work with him part-time or something to stay busy, I don’t — I guess I don’t have a definite plan, I don’t want to sit around, I want to remain active somewhere, but I don’t know what I can or can’t do, I guess that’s the problem. I’ll have to find something that, to hold a job, an eight hour, 10 hour job a day I think would bе out of the question. I’d like to get into something for myself but I just, I haven’t come up with anything. Maybe a little woodshop or paint shop or something, I don’t know, that’s what I keep thinking of.
{Id. at 43.) The ALJ’s written decision relies, in part, on this testimony. (Appellant’s App. at 12.)
We agree with the ALJ that Naber’s testimony is inconsistent with his complaints of disabling pain. Naber’s intention to return to work is laudable, but we are reminded that a person is not disabled unless “he is not only unable to do his previous work but [also] cannot ... engage in any other kind of substantial gainful work.” 42 U.S.C. § 423(d)(2)(A). Naber’s intention to work on his brother’s ranch or in a woodshop or paint shop tends to prove that he is able to work. Naber further testified that his condition at the time of the hearing was the same as his condition during the relevant 14r-month period.
{See
Tr. at 36). Thus, Naber’s testimony about his intention to work in the future supports the ALJ’s decision to deny benefits for the relevant 14r-month period despite Naber's complaints of pain.
See Polaski,
In addition, Naber actually performed medium-exertional work during the relevant 14-month period. A staff person at the Rapid City Veterans Administration Medical Center, where Naber lived during the relevant period, recommended that Naber be assigned to a woodshop for six hours of work per day. (Tr. at 370.) Naber testified that he was able to work continuously in a standing position for up to оne hour and that he had no additional difficulties so long as he could sit and rest occasionally.
(See id.
at 42.) The ALJ referred to Naber’s work in the wood-shop in his written decision.
(See
Appellant’s App. at 12.) Nabеr’s ability to work in the woodshop is, at the least, consistent with “light work,” which is defined as work that “requires a good deal of walking or standing [or] involves sitting most of the time with some pushing and pulling of arm and leg controls.” 20 C.F.R. § 1567(b). Bеcause “light work” does not involve constant standing, Naber can perform light work on a “sustained basis.”
See McCoy v. Schweiker,
Naber next contends that the ALJ erred by failing to call a medical expert to testify about Naber’s spinal disorders and his alcoholism and alcohol-relatеd depression. We have held that “[m]edical testimony is relevant in determining precisely what claimant’s physical impediments are, but it is not conclusive as to the ultimate question concerning whethеr the claimant’s injuries are so severe that he is prevented from doing productive work.”
Nelson v. Sullivan,
Here, other evidence in the record provides a sufficient basis for the ALJ’s conclusion that Naber’s alcoholism and alcohol-related depression was not a significant nonexеrtional impairment. Naber’s alcohol problems actually improved during the 14-month period from what they were before, when he was working.
(Compare
Tr. at 333-45
with id.
at 347-52.) Thus, the record supports the ALJ’s conclusion.
See Dixon v. Sullivan,
Naber last contends that the ALJ should not have used the Medical-Vocational Guidelines. If an ALJ finds that a claimant has nonexertional impairments that affect the claimant’s ability to do other work, then the ALJ cannot rely solely on thе guidelines to determine whether the claimant is disabled.
Jenkins v. Bowen,
This record contains substantial evidence that Naber’s nonexertional impairments do not significantly affect his ability to perform light work. “When a сlaimant’s subjective complaints of pain ‘are explicitly discredited for legally sufficient reasons articulated by the ALJ,’ the Secretary’s burden [at the fifth step] may be met by use of the
*190
[Medical-Vocational Guidelines].”
Hutsell v. Sullivan,
III.
The judgment of the district court is affirmed.
Notes
. The Honorable Andrew W. Bogue, Senior District Judge, United States District Court for the District of South Dakota.
. As an antеrior matter, Naber argues that the ALJ erred by discounting two affidavits because they are, by nature, less convincing than live testimony. The ALJ stated that he found it difficult to determine the credibility of each affiant, {see Appellant's App. at 13), but he also went on to analyze their statements under the assumption that the affidavits were true, {see id. at 13-14). The ALJ concluded that the affidavits could not compel a finding of disability, and we find nothing within them to seriously undermine the evidence supporting the ALJ’s decision to deny benefits prior to January 5, 1991. Nothing in the authority Naber cites (20 C.F.R. §§ 404.1520(a) & 404.1571 (1993)) requires an ALJ to give equal weight to affidavits and live testimony. Thus, we conclude that the ALJ's credibility determinations were not improper.
