Not really - life expectancy in UK is 81, and if you look at life expectancy at age 65 (which is probably more helpful as takes out the skews- i.e. people who die in childhood or young adulthood, usually of non-lifestyle related factors), expectancy is another 18-20 years. So the bog standard person who gets to 65 can now reasonably expect to get to 85. Those aren't all healthy ones. Those are ones that are going to get their hips done, their knees done, undergo cancer treatment, be on a cocktail for their hearts and blood pressure and diabetes, probably going to get dementia.
I probably do see the bleaker side of it as I work in the NGO sector/ see the statistics on the healthcare burden of an ageing population, but I just don't see a huge quality of life in many people over, say, 80, although of course there are exceptions, and maybe I'll be one (I definitely try to stay as healthy as possible- don't smoke, don't drink too much, keep my weight down etc) but it's not like its a talisman. I know I'd probably never be able to actually top myself, so I kind of hope I just die before I get sick. Wouldn't want to spend 10 years in a chair not recognising my relatives like DH's DGF.
I guess I feel that as a society we need to have a discussion around ageing and whether increasing longevity is really a good "goal".
Anyway, sorry OP, I know I'm derailing your thread. It's just something I give a lot of thought to.
