If this actually comes about, I would make it my life mission to eradicate the technology and anyone who knows how to duplicate it.
Doesn't anyone think this is a horrible, terrible thing? The entire human identity, since the first time we rubbed two sticks together has been definded by our relative lifespan. Age is the great equalizer. You can be the richest man or the poorest man, powerful or powerless, regardless of religion, nationality, skin colour, gender or whatever else, everyone lives for about the same amount of the time. Like I said, the great equalizer.
Eliminate ageing/dying, and all of humanity gets turned sideways. Society would be changed in a million tiny, but significant ways, which you don't really notice unless you stop to think about it.
Aldous Huxley must be spinning in his grave.
