Video games these days tend to assume you're young. In the case of the older people I've seen game, I think its one of the few times in their life where they can be interacted with, and their elderly (and in their case, varying degrees of sickly) status doesn't matter.
For the elderly, their world can be so small and passive; video games can be an opportunity to enjoy the culture at large, and have an active part in doing so.
