30,000 years or so ago the proportion of people who lived long enough to be grandparents skyrocketed – which may have been the driving force behind the explosion of new tool types and art forms that occurred at the same time, and may explain how modern humans outcompeted other hominids such as the Neanderthals.

Right now we’re experiencing just such another jump in life expectancy.

Judging from what happened from the last time humanity experienced such a jump, the life of our species may change radically. And this time we have the opportunity to direct that change.

So what are we going to do with it? Where do we want to get to?
