And that's the world's biggest problem: the future is seen as someone else's concern. - David A. Sinclair

The other test of age is the sitting-rising test (SRT). Sit on the floor, barefooted, with legs crossed. Lean forward quickly and see if you can get up in one move. A young person can. A middle-aged person typically needs to push off with one of their hands. An elderly person often needs to get onto one knee. A study of people 51 to 80 years found that 157 out of 159 people who passed away in 75 months had received less than perfect SRT scores.

This might be the least considered societal advantage of prolonged vitality, and it might just be the greatest advantage of all. Perhaps when we're not all so afraid of the ticking clock, we'll slow down, we'll take a breath, we'll be stoic Samaritans.
I would like to emphasize the word "perhaps," here. I will be the first to say that this thesis is supposition more than science. But the small-sample Princeton experiment both followed and portended a lot of other research demonstrating that humans are a lot more humane when they've got more time. All of the studies, though, take stock of how people behave when they have a few more minutes, or perhaps a few more hours, to spare.
What would happen if we had a few more years? A few more decades? A few more centuries?

The tragedy of the commons is that humans are not very good at taking personal action to solve collective problems. The trick to revolutionary change is finding ways to make self-interest align with the common good. For people to accept widespread biometric tracking in a way that could help us get ahead of fast-moving deadly viruses, they'll need to be offered something they have a hard time seeing themselves without.
