The question arose as to what we would do differently if we were immortal. […] I answered that I would travel more. Later the question was asked, what would you do differently if you found out you had only a short time to live. I answered again that I would travel more. Click, buzz, whirr…does not compute, does not compute. […] Given that I would travel more if I was to live either less or more, the probability that I was at just that level of mortality that I should not be traveling now must be vanishingly small.

Alex Tabarrok. Swap out “travel” for whatever it is that you happen to value a lot. (Got reminded about this post via Ben Casnocha.)
