you will be cycling in heaven buddy
Aye, if there is a heaven.
I don't think any of that exist, but I'll believe it when I see it.
Life is too short, I think that people who say otherwise are clinically depressed or are assuming that you would end up like Gandalf or something, when in reality any life extension would be the result of a slowing of the ageing process affording you more of the younger years. Everlasting youth is far off, but clearly exists in a number of other species and could be applied to humans in the future.
What species is everlasting youth present in? And if it is everlasting, why do they die?
