29 CFR Part 1630, Regulations to Implement the Equal Employment Provisions of the ADA (Title I Regulations with amendments issued through May 2016)

(iv) Given the rules of construction set forth in paragraphs (j)(1)(i) through (ix) of this section, it may often be unnecessary to conduct an analysis involving most or all of these types of facts. This is particularly true with respect to impairments such as those described in paragraph (j)(3)(iii) of this section, which by their inherent nature should be easily found to impose a substantial limitation on a major life activity, and for which the individualized assessment should be particularly simple and straightforward.
