I like variety in my game, and some form of disability would be fine with me. But not to reflect all realistic sides of it, I simply don't think a full focus would blend well with this game. What I would like to see is some logic relation between actual eyes state and the need of glasses. Also a dna generated need for the hearing aid we already got. Need of wheelchair could be a thing, I'm just not sure how it should be handled re need of it. One think I missed is that elders should have decreased abilities at a certain age, maybe depending on how they lived their lives, but also generic could play a role. Say, not walking any stairs, becoming clumsy, not able to read anything without glasses, using walking cane, having slightly crooked back etc. My real old elders are way too young ;)
I know OP refer to younger sims, but these things could come in the same pack. General disability might be too hard on many simmers - like you planned a so-ad-so family, and the disability might get removed in CAS anyway because it was not fitting the plan. If you want to spend your limited simming time playing a movie star, you might not really be up to playing a disability game instead. So this thing might need to be something we can toggle on/off somehow. But the smaller disabilities I'm all for as a genetic thing :)
