...because no one (that we know of) has done it before? I'm NOT saying living forever is something we should pin our hopes on or strive for or anything, though I'm also NOT saying it's a bad idea. But that's not the point.

Also, to put things simply, isn't the "key" to immortality simply "not dying"? I mean, if you just... don't die, you won't stop living. Or (I'm in grade school and have yet to take biology) is there something in us that runs out as we age, or something in us that accumulates as we age, so that eventually our bodies have to perish?

I'm simply curious

I am completely not a scientist and fail at anything science related. So this is going to be wrong or something, but the basic concept should be ok.

I read somewhere, notk nowing is this was true.. or anything like that, that because of the 'hayflicks limit' it is impossible to us to live past a certain age. Something about cells only being able to divide a certain number of times.. something like that.

That makes sense, and I think I've heard it before, as well. I wonder what prevents from dividing after a certain age? It must be they run out of something, or something accumulates in them.

No. Given that noone's managed over around 114 years old (certified, at any rate), it's a big leap between that figure and forever, which presupposes that our bodies become too frail. Without substantial scientific intervention, I doubt people could live beyond 200, let alone forever.

Even then, it raises questions about whether you'd want to and what state of decrepitude you'd be in.

I thought cell replication got slower as you got older hence why people age and die.

See what happens is that your cells simply get bored and quit living.
I mean wouldn't you get bored, just dividing, and dividing and dividing again? It's boring.
If you entertain your cells you will live forever.

Always read to your cells, play them music, take them to shows, take them absailing, play monopoly, teach them how to tapdance and remember to sit down with them and watch a bit of telly.

As you age your cells pick up imperfections, and every time a cell duplicates, it picks up more and more of these imperfections, until it has too many and it (and you) dies.
It's theoretically possible to live forever if you can counteract that, but good luck doing it.

There's a protein that caps your DNA called a telomere, imagine it's a piece of thread; everytime your DNA divides it gets shorter and shorter until there's none of it left and your cells can no longer divide= death.

Damn I've been trying to think for the last few hours what that reminded me of and now I remember!

In a book by Douglas Adams, he explained how people could fly. You jump off something, throw yourself at the ground, and miss.

I love this logic. :rofl:

so long as we live on earth, immorality is impossible. radioactivity is bad in high doses, but we are exposed to it all the time in smaller doses. radioactivity is what makes us age. so, the question might be how do we get rid of radioactivity? well, we can't unless we decide to ruin the planet, because radioactivity is what generates heat in the earth. and, well, if there's no heat on earth there's no life to begin with, much less immortality. it's one of the things where it's both good and bad.
