I think what he achieved for the money he put into it is the "baby-face" effect - some people are just looking (and actually biologically, being several years younger than the other), I believe I am one of those people (I can pass off as 32-33y old guy easily even if I am almost 40) this due to the fact that I had training routine since I was 16 years old until 35 (then I started to fail at it and that's where I really started feeling aging) and I am a "baby-face" type (sucked at high school, but its great now).
Now, the guy obviously is not in the gene pool of "genetically younger" people - it is obvious when you will look at his older photos - however he achieved that effect by putting a lot of effort (and money) into it. However I think he might be looking into some nasty collateral effects of what he is doing now, later in life (your body does not like so excessive changes in a relatively short period of time, body likes what I would call a "slow routine") that's why his face looks a bit odd and tbh I can tell he is into 40s - I would say he looks 42. So all his money and diet bought him 5 - 6 years (which some of us get as a "starter package" so to speak) and great looking teeths.
So its not like he is evading death - actually, I am quite sure he won't become centenarian - body is not a machine and we are all about to die - I agree that around 25th century humanity will achieve level of development that will allow to prolong life to a vast degree (well past 100 years biological stamp) but his approach is just too extreme and he is too fixated about it, also it is still early 21st century. He started eating healthy and training regularly too late. He also seems to overdo it and hit various diets/training programmes (changing them) too often (which is also inevitable for him, because he wants the best programme for his current state of health, and he is still getting older, right?).
His genes also tell me he won't hit 100 for sure. Sorry. You may become financially successful (he obviously is) but it will not change you on the biological level to the extent he proclaimes he achieves. It is probably an example of economics laws where efforts giving you 80% of his effects would cost you almost nothing (vs your current costs of living) but he decides to get additional 20% of health boost for millions (1-2mln?) of dollars per year (good for him if he can do it) except like I said, body is not a machine therefore works like machine only to some extent - if you have maintained it poorly until your late 30's, you will not make a full, clean, 100% turn around just because you decided to, applied business approach to it and spent a lot of money. Perhaps he will evade a heart attack, stroke or diagnose cancer early. That will be it.
