> Inborn in the sense that IQ is highly predictive of lifespan
IQ is only a bit more genetic than environmental (about 55-45, from most of what I've seen on the issue), so even if IQ was extremely strongly associated with lifespan, that would be a weak basis for characterizing the latter as being overwhelmingly inborn.
> Americans would clearly live a lot longer than they do if they spent less on healthcare.
That's far from clear; there's reason to suspect American food cut healthcare costs and do as well or better, but there is certainly no guarantee that blindly cutting spending would do that. If
