It seems in my 53-years that some poeople just live longer.. I have seen elderly people that seem to have a lingering illness-yet-I've been looking at them for some 10-years.. ..they just seem to be that way.. I have seen youth snatched from people/they died way too young.. I've seen two people that live together-yet-one passes and the other lives on in good health.. .. Diet..or food intake seems very apt to kill your "senses"..First/later the Acorn falls near the tree..we can be accepting of such easy realities.. .. I have actually increased my food intake..and become more active in the process..my sleep is perfect..and I use that to feel my way along.. .. The rest is taken care of by Hygiene.
