Should we tiptoe through the world cautiously, to give ourselves the chance to live for a few years or even a decade longer? Or should we dive head-first into whatever turns us on, and risk having it all cut short? Does the question even matter since we can't know whether our decisions made any difference? If living a dramatic life doesn't kill you, you might just die early anyway, sitting at home.
We're very small creatures and we've only been keeping track of our own history for a tiny slice of time. Makes you wonder what we were doing before that, and whether we might have been happier not bothering with it all. It's hard to fathom that people walked the planet for two hundred thousand years before the first pyramid was built.
