50s you can still be pretty strong and endurant, provided no accident/degenerative disease happened. I would expect tribe of anybody but mindless savages would often protect their older if only due to their experience in survival (but maybe we were pretty much mindless savages during most of our evolution). 60s is when any remaining strength takes nose dive

Isn't that given modern nutrition, hygiene, water access, tooth cleaning etc?

The other commenter said that people that survived childhood during these times usually were expected to live around 54 years.
