David Sinclair: Can Aging Be Reversed? After 8 Weeks, Cells Appeared 75% Younger In Tests!

A huge number of businesses have spent the last few years adopting AI, and my company, steven.com, is no different. But here's the thing, most companies actually have no idea whether or not it's working for them. Their teams might be using AI, they might be spending money on AI, and their leaders might be telling the board that they are an AI-enabled business, but they'd also likely struggle to explain where in the business AI is helping. The issue is there's no easy way to see whether it's delivering value or working effectively unless you're using our sponsor, Liridin, which runs seamlessly as a browser plugin or desktop agent and shows you exactly how AI is being used across your organization, what it's actually producing, and where the real opportunities in your business are. That way, you're able to make data-backed decisions instead of just guessing all the time. I love anything that kills the guesswork. So if you want to be a company that's informed with your use of AI and accelerate your company's AI transformation, head to liridin.com and book a demo now. That's larridin.com and book a demo now. This is very...

It's bad, right?

**Steven Bartlett** (1:04)
It's hard, yeah.

That's what it's like to be old. And for far too long, we've ignored it or accepted it as natural. And I reject the idea that aging, just because it's natural, is acceptable. Dying at 80 is not inevitable. Absolutely, that can be changed. So if you're skeptical, I am a Harvard professor who has been studying aging, longevity, and age reversal for 30 years. And I've seen enough from my lab showing that we can literally now reverse the aging process. And it's not a question of if, it's a question of when this is going to happen. And everyone should stick around, because I'm going to tell you some of the major things that people should be doing. They can lengthen your life by a decade. Hey, you're not taking that off, Steve. You've got 10 minutes of that. So you can accelerate aging by smoking, getting an x-ray, ultra-processed foods, excessive drinking, flying a lot.

**Steven Bartlett** (1:47)
I fly all the time.

That's probably accelerating the aging process. Even going to a rock concert and blasting your eardrums because your ear hair cells are getting older faster. And so I look at the body like it's a computer and we can reinstall the software. And what's interesting is when you reverse aging diseases like Alzheimer's, cancer, heart disease go away or are cured because what's driving a lot of those diseases is aging. And so my lab is like Willy Wonka's Chocolate Factory. They are making discoveries that blow me away every week. And I think we're at a turning point in human history where you're probably going to live into the 22nd century if you do all the right things.

And we're going to dig into all of those in great detail. But what are the unintended consequences of such a world where we all live longer? And also, do you think it's going to be possible in the next 50 years for us to live forever? And then what's the best treatment you've discovered for hair loss?

This is why I love your podcast, Steven. You asked the right questions. So first...

Guys, I've got a favour to ask before this episode begins. 69% of you that listen to the show frequently haven't yet hit the follow button. And that follow button is very smart because it means you won't miss the best episodes. The algorithm, if you follow a show, will deliver you the best episodes from that show very prominently in your feed. So when we have our best episodes on this show, the most shared episodes, the most rated episodes, I would love you to know. And the simple way for you to know that is to hit that follow button. But also, it's the simple, easy, free thing that you can do to help us make the show better. I would be hugely grateful if you could take a minute on the app you're listening to this on right now and hit that follow button. Thank you so, so, so much.
Dr. David Sinclair, I have waited many years to speak to you. And I've been so keen to speak to you for so many years because so much of the research and the information I've consumed on the subjects we're going to talk about today comes from you, directly from research you've done and from theories and ideas and hypotheses that you formed. I think the place that this conversation should start is probably with this picture, because it appears to be incredibly formative in your journey.
