that's what the regeneration process is for. and you only get 12 of them so don't waste them by falling off the top of a radio tower or be poisoned by gas.
in all seriousness, I very much enjoyed your comment. In my opinion, I think it would be great if we could somehow make the process of aging less uncomfortable for our last half of our life while keeping our natural lifespan more or less the same 70 +/-. But if we can find cures for alzheimers, skin cancer, etc that would be great for our quality of life. But where do you draw a line between anti-aging and cures for diseases such as these?
