I'm not aware of any plains with bountiful mammoth and fruit trees that I can colonise with my hunter-gatherer tribe, but then I'm not an expert in Google maps ;)

Nonetheless, i'm not sure that the last ten years of my Dad's life (suffering from vascular dementia) were particularly good for him (I know that they were super hard for the rest of us).

I think the general point is that it's hard to trade-off the quality of those extra years, which is the point I was trying (unsuccessfully, it appears) to make.
