A few years ago I read a great online short scifi story about a boy (either in high school or college) who kept wondering what the point of life is. The story then describes how immortality became fact through medical and technological advances and proceeds to follow the boy throughout billions of years until he finally witnesses the end of the universe.
I've searched for hours on the web but can't find the story. If anyone could direct me to it, I'd greatly appreciate it!
First of all, thanks to all the links and suggestions. I've read some great scifi thanks to you guys! But unfortunately I still haven't found the story I was looking for, though I spent many more hours looking on the web.
