Damn Bunker, you critically hit the english language quite often.
Stopping the are process and gaining the ability to recreate your cells for an eternity is not possible, nor will it ever be without any type of constant medicine/body implants. Even if there is a way for this to be done, it's not in the near future, and it most defenatly is not immortality.
We spoke about this in our Biology class a while ago, and I asure you, the cells alone do not fully controll your body. There are other type of factors. (This is to Prozac :b)
"Immortality is the concept of existing for a potentially infinite or indeterminate length of time." -> Again, even if you found a way to never die of natural causes you would still be far from immortal. Half of the people in this world don't even die of natural causes anyway, which again means you would still die ;<. And whenever you can die, from whatever at all, you are not immortal
.
Mmmmmm pie.
