parts of the statute’s definition of disability: First, the EEOC must demonstrate that Shepherd’s impairment limited a major life activity, for which we examine the law and the evidence regarding Shepherd’s ability to care for himself. See 42 U.S.C. § 12102(2)(A) (2006). Second, the EEOC must further show that his limitation on a major life activity was substantial. See id. We identify disputed issues of material fact with respect to both parts.
A. Limitations on Self-Care
Self-care has long been recognized as a major life activity under the ADA. The federal regulations adopted in the year following the passage of the Act listed “caring for oneself’ as a major life activity. See 29 C.F.R. § 1630.2(f). Courts followed suit. See Holt v. Grand Lake Mental Health Center, Inc., 443 F.3d 762, 767 (10th Cir.2006) (recognizing self-care as a major life activity under the ADA); Regional Economic Community Action Program, Inc. v. City of Middletown, 294 F.3d 35, 47 (2d Cir.2002) (providing examples of limitations on self-care); Cehrs v. Northeast Ohio Alzheimer’s Research Center, 155 F.3d 775, 780-81 (6th Cir.1998) (identifying caring for oneself as a recognized major life activity under the Act); Dutcher v. Ingalls Shipbuilding, 53 F.3d 723, 726 (5th Cir.1995) (caring for oneself encompasses a broad range of normal activities related to daily living, including feeding oneself, driving, grooming, and cleaning home).
We ruled in Nawrot v. CPC International, 277 F.3d 896, 904-05 (7th Cir.2002), that an employee’s inability to administer his own diabetes medication also amounted to a limitation on the major life activity of self-care. Likewise in Brunker v. Schwan’s Home Service, 583 F.3d 1004, 1008-09 (7th Cir.2009), we found that not being able to dress oneself appropriately constituted evidence of a limitation on the major life activity of self-care. Our application is consistent with the purpose of the ADA to “provide a clear and comprehensive national mandate” to combat disability discrimination. Americans with Disabilities Act of 1990, Pub.L. No. 101-336, § 2, 104 Stat. 327, 329; see also ADA Amendments Act of 2008 § 1(b), 122 Stat. at 3554 (elaborating on a broad scope of protection intended by Congress to be available under the original Act); Sutton v. United Air Lines, Inc., 527 U.S. 471, 495, 119 S.Ct. 2139, 144 L.Ed.2d 450 (1999) (Stevens, J., dissenting) (noting that the ADA was meant to serve a remedial purpose). The specific inclusion of “caring for oneself’ in the 2008 Amendments’ list of major life activities further supports this interpretation. See ADA Amendments Act of 2008 § 4(a), 122 Stat. at 3555, amending 42 U.S.C. § 12102.
Shepherd testified at his deposition that he needed assistance with dressing himself, brushing his hair, and bathing four or five days each week while he was working at AutoZone prior to September 13, 2003. He also recalled experiencing other difficulties since 2003, including an inability to tie his shoes and the development of oral hygiene problems that resulted from his inability to care for his teeth properly. Shepherd’s wife, Susan Shepherd, also testified that she had to assist him with personal care while he was working at AutoZone. According to her deposition testimony, she had to help Shepherd with showering, putting on his pants and shoes, and brushing his hair and teeth before he stopped working for AutoZone.
There is some ambiguity in Susan’s testimony regarding exactly when Shepherd began having difficulty with certain personal tasks. Though Susan said she assisted him with his personal tasks “before he stopped working for AutoZone,” at oth
