science and medicine mostly prolong life or save lives. they can (in a very limited manner) help somewhat with tiredness at old age. healthy brain function is not improved that much with the help of health industry.
and we need those who their thinking is not fossilized. I don’t mean that as insult, it is just they way of life.
as I said they can of course be advisers.
are you saying most 110 years old are capable of holding highest offices? like house of representatives? they need to move alot and talk to alot of people. it is very tiring.
if not at 110 then at some age most of us are not really gonna be great at those “jobs”.
and another side to my point is that old people are gonna set in their politics and also is they survive the politics circus (many many terms) then they become like a family so they are not gonna rock the boat, so they usually become THE status quo. look at Bernie and his support for jewish isis.
also they are not really good at fixing new problems (or even old ones) with new tools.
I don’t think that is how it works. For example I don’t think you can get google security update for older android without updating the whole system. there were monthly google security update that are going to become less frequent.
Also I think the part that stops the apk installation (those not signed with signature in google database) are checked by google play services and that is installed in background which is the result of project treble and mainline that google implemented for modular updates without rom update. so you probably can’t stop google from doing this policy even if you stay on older ROMs.
