Well, I would have said yes before reading Skathac's post. But now I can't get the mental image of being trapped in a cramped safe in the bottom of the ocean for eternity out of my head. >.<
In a more optimistic sense, however, assuming that my aging would basically pause, and assuming that there was SOME way that I could possibly die (i.e. stabbed through the heart, decapitated, saying, "I take it back!") I would definitely want to live forever. I don't believe life would lose its meaning and I definitely don't believe there's "only so much" to experience. The world is huge! Not just geographically but also in terms of what it contains. Not a day goes by that I don't wish I had more time to do all the things I want to do, explore all the places I want to explore, learn all the things I wish to learn.
I'm also of the belief that when I pass away, there's no shiny happy afterlife. I will simply cease to be. And that idea is the most frightening concept I can imagine.
The only downside, imo, would be, as others said, watching the people I know and love die and not being able to grow old and live a normal life with someone I loved.
And hi btw. =) New to the forum. Blame Skoffin.
