Nancy,
We all take turns cooking, sharing the cost of cooking, and chores, usually eating communally.
If a person's condition allows them to cook for everyone's condition and needs, then it doesn't matter what malady they are dealing with.
If their condition, however, requires that they focus on themselves, then they'd be better off, living in an environment, conducive to that.
Does that answer your question?
Thank you, very much.
