Playing God.
Not going to happen.
Short of perpetual stasis or suspended animation, human life was meant to be finite.
The sooner those seeking the fountain of youth, etc. figure this out, the better off we will all be as a species.
I went to a funeral once where the preacher said "We're meant to LIVE". I thought of that as a profound statement, since that really is how the human body is tuned. I ultimately think aging and death can be overcome, but there are HUGE consequences to doing so, e.g. no more generational shifts (although that one may be a good thing given how America has changed since the '60's)
No one can have as many babies as they can afford, how will the 200 year olds that have retired support themselves, what about those that have had joint replacements or stents (how will reversing the aging process help them) etc, etc. There will be a lot of unintended consequences that no one has thought of.
It will be painful in a lot of ways, despite the never ending human search for immortality, or at least a fountain of youth.
There is a time to live and a time to die. GOD has the final say.
However, in Matthew 24 it says as in the days of Noah, so will it be when the SON of man returns. Will today’s average lifespan be extended to the length of lifespans ‘as in the days of Noah’?
