I am not afraid of death because I know that there's nothing after. I'll be dead, I won't feel or care about anything, and that's fine by me. Sometimes it's desirable.
Sometimes, though, I feel like I want to live forever, not out of fear of death but out of curiosity about life. I wish I could hang around hundreds or thousands of years to see what's going to happen. It's like I've been given the greatest book every written, and been allowed to read only a brief chapter in the middle.
I feel exactly the same. I am scared of illness, and pain, and old age, but I am not really
scared of death: I won't be there to suffer any ill from it. I am, however,
mighty pissed off at death. All the things I will never do, all the stuff I will never learn, all the people I will never meet.
That piss me off big time.
I have an interest in palaeontology and evolutionary biology; looking at the world through geologic time comes with that. Too many people (probably more especially the very wealthy) concern themselves with their "legacy" and "being remembered," but the fact is that in the fullness of time our deeds and even our species will likely be little more than a footnote in history.
I'm a cosmologist. Contemplating the
entire history of time makes you feel pretty negligible, I tell you.
But at the same time, I feel very deeply the uniqueness of myself and how unrepeatable my life is in the great tapestry of the space-time (I have a feeling this won't come as a surprise to people

). Even if the universe keep running forever, it will never be another
me (Omega Point scenarios excluded). So the only "legacy" I feel the need to leave is my own life, lived exactly in the way it was (and it will be) lived.
My own very existence, a naked ape ape on a utterly insignificant little blue-green planet, orbiting a small unregarded yellow sun in the uncharted backwaters of the unfashionable end of the western spiral arm of one of the thousand billions galaxies in the universe, altered the state of the universe, irrevocably. Nothing can change it. My life will resonate in the fabric of the universe, forever.
The iguana wuz here. The universe will remember it. And will think of it as "the good times".
