What is there to be afraid of about death, exactly? If you don't believe in any afterlife or continuation, then there will be no consciousness to perceive the other side of death.

If you do believe in an afterlife or continuation, you'll have spent your life preparing accordingly.

For me the problem is not death itself, but the steady decline that usually comes before it. Biologically immortal humans would still die eventually, but there wouldn’t be decades of old age before death.

Because I don’t want to stop existing. I want to be able to see my daughters (and hopefully grandchildren someday) grow up.

Sure, once I’m dead it won’t bother me, but I’m alive right now and it does.
