Cancer could very well be the fountain of youth.
It's one of only two kinds of cells (that I know about) that can continue to grow and divide well past the limits of other cells.
Cancer is life, unbound, no? If we ever found a way to direct and control the growth of the cancerous cells, we could have a self-repairing system
that continues to function for decades or even centuries longer than the one nature gifted us with.
It's a pretty cool thought.
