And so I'm chronologically 47 years old, but biologically my left ear is 64 years old. My heart is 37. My diaphragm is age 18. So organs age at different speeds. And so for example, my left ear is very old because I shot a lot of guns as a kid, exposing my left ear. I would tuck in my right ear and expose my left ear and I also listened to a lot of loud music.

And so between 4,000 and 12,000 Hertz, I'm basically deaf.

so once you have a baseline of the biological age of every organ in your body you can then say okay what is the scientific literature about reducing the age like can i make my left ear not 64 but 63 or 62 or 42 or 41 and so we've taken that approach across my entire body so everything you've listed listed off is a scientific evidence-based approach on how to reduce the

the biological age of the organs of my body. And so we're trying to get my body to be age 18 across the entire body, which right now is a really crazy endeavor. We're just not there yet, but that's what we're trying to systematically engineer.

Philosophically, I'm indifferent to where the idea comes from. It can be an ancient practice. It can be a new scientific study. It can come from anywhere. The only thing we care about is that it works and that we can measure it. So health is really built on folklore, antidotes, storytelling. I mean, that's how it's really been built. And what we're saying is that the power is a measurement.

Like, for example, if you look at a smartphone, a smartphone can't be built by storytelling. It's got to be built by rigorous precision in engineering and measurement. If you couldn't measure and you couldn't go through this quantitative process, there's no way you can build a smartphone that works. And the same approach is true with the body.

You can't go through a rigorous process in trying to de-age the entire body by telling pretty stories. You have to actually measure the cellular function. You have to look at the actual organ function. You have to see the biological systems. So the breakthrough with what we've done is I've become the most measured person in human history. Like we measure- That I think is true.

Yeah, we measure everything. And so if someone says, you know, like I have the following theory, we say, great, we're going to test the theory out and we're going to generate all the data. And so it's really very few things for life are going to survive without quantitative measurement.
