20 CFR 404.1520(d) states that the Claimant will be found disabled if the impairment meets the duration requirement and is listed in Appendix 1 or is equal to a listed impairment.
20 CFR 404.1525 states that the Listing of Impairments describes, for each of the major body systems, impairments which are considered severe enough to prevent a person from doing any gainful activity. The evidence must show that the impairment has lasted or is expected to last for a continuous period of at least twelve months.
A Claimant who is not currently engaging in SGA and who has a severe impairment which meets or equals a listing, is entitled to disability benefits. Edwards v. Heckler, 736 F.2d 625, 628 (11th Cir. 1984). A Claimant whose impairment meets a listing is disabled regardless of the fact that he or she has worked in the past with the impairments or could return to his or her past work. Powell on behalf of Powell v. Heckler, 773 F.2d 1572, 1576 (11th Cir. 1985).
