It's a bit difficult to correctly translate it in English for me but I will try to summarize what I think.

To me, life and death are the two faces of the same coin, they aren't opposite but complementary. Life would have no flavour, no meaning without death. It's because of its fragility that life is so precious and magnificent. I have read a book where angels were jalous of humans, because death was a gift God gave them, in order to give their life more interest. That makes sense for me.

So, artificialy trying to prolong it (what is already a real problem in today way to practice medecine), without first trying to improve the way we live and act as spiritual individuals, would lead IMHO to a trainwreck. The acces of such a technology would certainly be limited to richest people, triggering anger, perhaps riots...

Definitely not a good idea to me!
