I've posted here a few times before on the topic of longevity and how I believe it is important to consider and plan for a life span most of currently think impossible. And a lot of people have expressed skepticism - which is certainly understandable.
Anyway, one of the things that makes me so certain that extended lifespan is for real is the fact that we have technologies available
today which can slow many aspects of the aging process to a crawl. Those technologies are mostly what I'd call "First Generation" technologies - meaning they produce the intended result but they also bring nasty side effects and have severe limitations. I would expect subsequent technologies to produce better results with fewer side effects and risks.
So to demonstrate the current state of the art in life extension, check out the pics below. The gent in the pics is a famous bodybuilder named Serge Nubret. The pics were taken just after he turned
66 years old.
Obviously, Serge is unlikely to fall down and break a hip any time soon. Of course, we can also assume he is taking a ton of anabolic steroids. And that is what I mean by a "First Generation" technology. Steroids have nasty side effects and can cause liver problems and other awful issues. So they obviously aren't the best solution for slowing the clock. I expect better solutions will become available as time goes on. But until then, the technologies currently available obviously work. I can't even speculate as to how long Serge will live - and live well. He is truly breaking new ground - our species has no prior experience with which to measure his success.
