We have a culture to live life as if to survive, hush the idea of death
Human activity is designed largely to avoid the fatality of death, overcome it by denying in some way that it is the final destiny.
Death is always on the way, but the fact that you don't know when it will arrive seems to take away from the finiteness of life. It's that terrible precision that we hate so much. But because we don't know, we get to think of life as an inexhaustible well.
