> I was pointing out the work they were doing on a regular basis as "older, less physically able" people.

I never said they were disabled. I just meant, they'd be less motile and likely to work on clothing, crafts, homesteading, care of the children, maybe even cooking and leading the tribe/group in religion and/or study. Given they'd have more experience and wisdom, it makes sense the elder of the family structure would be more closer at home to lead the way.
