Muscle mass and being active ndio inadetermine independence in old age kuliko savings,children,cholesteral etc.An old guy amekuwa active throughout his life will need less help all other things being equal compared to a rich guy amekuwa sedentary most of his life.
One fall ukiwa 70 unaeza kuwa disabled kama muscle mass yako iko low.

I think the best life ni ukiwa around everyone ie, young,middle aged,old,uneducated,rich,poor,etc.Kuishi in a normal mtaa where everyone is.Hii hapa mtakuwa isolated na thinking yenu mkireminisce old times na your peers.Take for example an old guy alijenga Kamulu akiwa mdogo, old age in his neighbourhood kuna new generation,new people from rural areas ata kama haongei na wao anatoka hapo nje kwa gate anaota jua au anatake a walk akiobserve the changes in life.
I think its the equivalent of how people from western and rift valley hukuja nairobi alafu wanajigroup na tribesmen wao kutoka huko unstead of being friends with everyone.
