This is a bodybuilding forum. If your goal is simply to try to live longer than everyone else, I would suggest buying a bubble to live in and getting the rest of your meals through a straw from now on.
Bottom line, everyone dies. No matter how young you think you are or how strong, eventually, you are going to die. I personally would rather live for 8 decades, enjoy my life to the fullest and make an impact on the world (possibly even write a few books or do something worthy of having one written about me) than simply try to live the longest for 10 decades in a much weaker, less experienced body.
Quality over quantity.
