From the day we are born, we only get about 1,000 months of life on average. That might make us feel a bit cheated. Why must we DIE? Oliver Burkeman reframes:

Why assume that an infinite supply of time is the default, and mortality the outrageous violation? Or to put it another way, why treat four thousand weeks as a very small number, because it’s so tiny compared with infinity, rather than treating it as a huge number, because it’s so many more weeks than if you had never been born? Surely only somebody who’d failed to notice how remarkable it is that anything IS, in the first place, would take their own being as such a given—as if it were something they had every right to have conferred upon them, and never to have taken away. So maybe it’s not that you’ve been cheated out of an unlimited supply of time; maybe it’s almost incomprehensibly miraculous to have been granted any time at all.
