I'm sure if you live a full life where you are constantly learning new things and having new experiences you can reach old age with a lot of mental elasticity and a wide-ranging perspective. Problem is, many people seem to narrow their perspective and close off to new experiences after a certain point, usually after they have children--at least the older people in my life do. So I suspect what's going on in the study mentioned is a bit of sample bias. The great advantage of youth is that there are endless possibilities you can be molded into. Which is probably something SV investors look for.
