trerro: hubiestubert: So, he eats well, exercises and keeps stress down?

That's not 'reducing his age.' That is just 'taking care of yourself', which $800M can do for someone.

We are likely going to crack the aging riddle within a century or two, and maybe even have some treatment that will allow for extended lifespans in another fifty years or so--beyond, 'eat right and exercise and have regular check-ups.'

Fetal tissue injections, magic herbs, electric fields, it's hookum and smoke, but that is hardly a new thing. Though, maybe if we could convince a few billionaires that infusions of quicksilver would make them immortal, the world might be a better place in a few years.

There's also the concept of "aging escape velocity", where you're still alive when one of the lifespan extensions hiats, which buys you enough time for another, which buys you more time, and so on, so even if it takes two centuries, you're actually around to see it. It's all a matter of how fast lifespans go up, and when they start to do so, obviously the younger you currently are, the better the chance you'll make the cut-off.

That said, yeah, anything already on the market is snake oil. Some serious research is going into this, some of it with promising results at least in mice, but there's nothing in human trials yet, and currently nothing approved and released.

trerro: johnphantom: No human living will live longer than 125 years. It would take recoding our genetics to create a new quasi-human will more regenerative abilities, at very least for our brains which could be transplanted.

We already have the ability to recode our genetics:

As that method improves, and newer ones are developed, total custom editing of our genetic source code is a very real thing that's being figured out now, with modern tech. So yes we need that, but no, that's not sci fi anymore, it's current science.
