Death

I've been dead for 13.730.000.000 years already (Aprox. age of the universe). Only the last 25 years I've been alive.
Therefore I don't fear death, since I can't recall that the previous 13.730.000.000 years were unpleasant...
For me death is the same state as before you were born, there is nothing, just eternal nothingness, just nice relaxed and calm.

Your body has not experienced the 13.730.000.000 years, (your) soul might.

Death is unknown, as of today. Most likely it will be unknown forever.

I'll not be a person thinking I'm cool if I say I'm not afraid of death. I'm afraid of death. I don't know what it's like, I don't know anything about it at all. It may be cool and stuff, but it might be horrible, and it may actually be flames licking your skin where you're going, forever. I prefer being on earth because I feel more secure in that way.
