I'd rather die after 100 years (though I'd prefer 500) than live forever.
I don't think some people realise how long forever is, or at least don't attempt to grasp it. How long before you get bored of your favourite hobby? How long before you get bored of your home? How long before you've seen and done all there is to do? Eventually you'd go insane with boredom.
"Hell is eternity stuck in a room with your friends". I don't know who said it, Holly can't remember in the book "Red Dwarf" (that being the joke, he's a computer with an IQ of 6000), but the point has merit.
first, eternal life in heaven (if it exists

lol) wouldnt be anything like earth... youd leave your physical brain behind... your physical brain gets tired of things
second, forever isnt possible... theres always some chance (maybe miniscule) that youll die, i think the odds would be against people living too long, there are many of ways of dying besides aging and in an infinite amount of time one of them would have to happen sometime)
when he says live forever, i think he means live as long as you want, with an almost insignificant chance of death until you feel like stopping the regeneration of yourself and letting yourself die
and... 500 or 1000 years in the future, will our brains be like they are now? i think many people will utilise technology (maybe chemical?) that increases empathy, intelligence, motivation, curiosity, etc... and new technological inventions would probably keep us entertained until our creativity stops (is that even possible)
so... id like to live as long as i want. maybe in a few hundred, or thousand years, i would want to stop whatever technology is keeping me alive, maybe i wouldnt. but id like the choice to remain alive as long as i wish
