I shot a lot of guns as a kid. And so I would, you know, aim the gun like this with this left ear exposed sound, this, this, it was more protected and then also loud music. And so, yeah, so this is the thing is like now when I'm at social events, I have this app on my phone decibel where like last night I was at a social event and the room was 105 decibels.

So anything over 80 can cause hearing damage. So just in a social environment with people talking in a voice that's like loud enough for the other person to hear, you've got sustained ear hearing damage.

It's huge. Entirely true. And we've tried for the past few years. So we take all these measurements and we say like, what is the biological age of blank organ? And then we say, all right, now we've reviewed all the scientific literature that's out there. How do you either slow down that speed of aging or reverse aging damage?

And then we say, all right, now we've reviewed all the scientific literature that's out there. How do you either slow down that speed of aging or reverse aging damage?

So, for example, with my left ear, we've said, can you take my left ear from age 64 to age 63 and 62 and all the way down to age 18? And so in that case, we've had no success with hearing. There are a few stem cell therapies that are in research, but no effective treatment. So we've had no success at all. So once you lose it right now, it's gone.

Whereas other parts of my body, like my speed of aging and my heart and my lungs, we've had great success lowering that biological age, if you look at it anatomically or functionally. And so some things we've had great success, but this is the point where When people look at me and they say, the guy is so busy trying not to die, he's forgetting how to live.

And the flip side of that is when you lose function,

movement eyesight hearing right your life begins to deteriorate two degrees like your mother saw in ways you can't even imagine and so it really is like this respect for our conscious existence and our biological capabilities and so really i think that's what i'm trying to do is that the new virtue is caring for our conscious existence and not being whimsical and throwing it away with behaviors that just are not necessary

I guess this is, I think, the coolest question right now is that in previous time periods, you were born and you died in predictable fashion. There was nothing you could do to stop the process. And so now what's different is that we are making progress on age related decline, even before a baby's conceived. So now there's embryo selection, right? So it's, don't die is happening before conception.

And then recent studies have shown that you can take a mouse and it's like last week of life and regenerate it and double the lifespan of that mouse. And so we have technologies that can extend life before conception, midlife, and even at the end of life. And so now that's, I'm saying this is really, it's full spectrum.

that there is no point of no return at this at this moment i mean in this moment yes but like increasingly it's becoming this open question is there and i think that's the most interesting and exciting thing my dad is 71 i think most of his friends are just like we're getting close it's almost time but man he's got this ferociousness to live life that i'm really inspired by

I don't think that any human can say anything intelligent more than one year from now. We can say we think the Earth is going to continue to orbit around the sun with a certain degree of stability. In terms of how long are we going to live... How will cultural norms persist? What will be normal? What will not be normal?
