I’m not so sure. If you look at Near Death Experiences, there are suggestions that an afterlife might exist. On this front I’m agnostic and keeping an open mind.

That existence is so brief encourages us to seize the day...

I am not much interested in afterlives. The concept is not meaningful. If time is an illusion the entire chain of organisms can be thought of as a single entity.

The only thing about us really worth immortality is conscious awareness, and that is common to us all—it is what we are in fact, and it can not die.

Part of you does live on especially if you had and raised children. You're passing on your DNA which is basically the essence of you are plus you've downloaded considerable personality traits into your kids.

Dying is like last of the ninth, two out, and you just swung and missed the third strike. Game over. No extra innings.
