Appellant petitioned the district court pursuant to 42 U.S.C. Sec. 405(g) for review and reversal of a final decision by the Secretary denying appellant’s application for Social Security disability benefits and for establishment of a period of disability. The sole issue was, and is, whether there is substantial evidence to support the administrative determination, for if there is, the administrative decision must be affirmed. *485 Celebrezze v. Kelley, 331 F.2d 981 (5th Cir. 1964); Clinch v. Celebrezze, 328 F.2d 778 (5th Cir. 1964) (per curiam); Celebrezze v. O’Brient, 323 F.2d 989 (5th Cir. 1963). On the administrative record before it the district court, in a well-written, thorough opinion, 1 answered this question affirmatively and granted summary judgment for the Secretary. The record discloses the requisite substantial evidence; it follows that judgment was properly entered for the Secretary, and accordingly that judgment is affirmed.
