90 is not that old these days. Both of my parents have reached their 90s without doing anything like this. Let’s take a look at that guy in 20 years and see how he is doing.
> 90 is not that old these days True but Hong Kong life expectancy for men is 81.3 years so one should still consider this evidence in favor of the man doing something that extends his lifespan. Doesn't need to be smoking-gun level but still: update your priors.

"Someone slipped up the distinction between years and generations and a legend was born" still seems enormously more probable than anomalous longevity existing but somehow never making it into the wider gene pool.
Do you (they) mean "distinction between years and months"? That would be between solar cycles and lunar cycles: seems enticing. That would make Methuselah 80yo when he reportedly died; but there are problems still as Seth (for example) became a father at 105, which if it were months would be 8¾ years. Another possibility is that when it says Methuselah it just means "Methuselah's blood line" or "Methuselah the tribe"…
Since it seems like the upshot of all of this is that Katcher is claiming to have discovered a set of signalling molecules which, when injected, rejuvenate tissue and presumably lengthen life, it runs into one of the most fundamental objections that can be leveled at theory of aging (or cure thereof): of the billions of humans that have existed, how is it that none of them have possessed a mutation which (in this cas…

yes. you need to reproduce and to ensure your offsprings reach sexual maturity. but humans are in no way special. we believe we have escaped our biology because of the cultural stratum we posses (ie exchanged memes for genes) but we are still basically animals.
Why couldn't it be true that we want to survive to ensure our grand-offspring and great-grandoffspring reach sexual maturity as well? That's a valid strategy (with tradeoffs, as there are with everything)

Someone I work with looks very youthful for their actual age, and that isn't always a good thing. When the team went on an offsite morale event jet skiing, he was told by the proprietor that he couldn't participate because their policy requires you to be at least 16 years old. He was 27 at the time. He never lived that down with his peers. When he tries to go to a bar with friends, he's sometimes accused of trying to…
I think people age at different rates. My Dad is in his mid 80's and plays four hours of sports a day, or at least he was before the pandemic hit. When I was in my mid-20's I had to impress the hell out of potential clients to get work, as I looked like I was 15, and girls my own age wouldn't look at me as I was too young. I never drank, so bars weren't an issue. When I was in my early forties, 15-20 year old girls w…
In general I’ve seen a lot of people that look young for their age but when looking at their skin up close on their face, neck or hands it gives it away. Women are also at an obvious advantage through their use of makeup.

One of my most favorite sci-fi movies explores this idea [0]. It's very intriguing and quite entertaining. [0] https://en.wikipedia.org/wiki/The_Man_from_Earth
I just commented before seeing your mention of it. Although I didn't realize until I commented that Jerome Bixby the author of The Man From Earth was also a Star Trek writer.
It's impossible for an old cell to become young again, at least with our current level of technology, because that would require you to reverse all the mutations that have built up over time in that cell. If your argument is that our bodies have many different repair mechanisms, and that as long as we can figure out how to activate them properly, we can then reverse aging, I would caution you that while you're correc…

The implication of the article is that the treatment may not be extremely costly. Idk why you immediately start talking about billionaires. The divide would likely be between the poor and the middle class.
A vial of insulin costs $6 to manufacture, but up to $300 to purchase without insurance. Simply because the treatment is inexpensive to manufacture does not mean it will be affordable to average humans.

At risk of sounding absolutely insane: There's probably no way to prove that this hasn't happened. Anyone who realizes they're not aging normally would likely have taken on a new identity elsewhere for fear of: 1. being burned at the stake 2. being trialed in repeated experiments 3. being deified, and then subsequently being burned at the stake. --- I realize my comment sounds like a joke, but I'm entirely serious.

And the same argument applies to true magicians btw.
When you could summon real magic, why should you reveal that to others?

But I doubt it.
From a perspective of evolution, aging and dying and new borns, make sense, because the environment changes. And youth is able to adopt better to new changes.
