memento mori

is the injunction to remember death, suggesting that because, without a doubt, our lives would be completely different if we knew that we were to die in a half hour, it should follow that, when viewed against the infinite measure of death, knowing we have instead a half a century should hardly be viewed any differently.

Memento mori-remember death! These are important words. If we kept in mind that we will soon inevitably die, our lives would be completely different. If a person knows that he will die in a half hour, he certainly will not bother doing trivial, stupid, or, especially, bad things during this half hour. Perhaps you have half a century before you die-what makes this any different from a half hour' Leo Tolstoy
