We said like, what does the scientific evidence say about longevity and things that make you die?

And then I measured every organ of my body that I could.

Like we would go through and say, what is the age?

So I was 42 years old when we started.

So I said like, what is the biological age of my heart?

Because your biological age can be different than your chronological age.

So for example, like my ear, my left ear is age 64.

Okay.

because I shot a lot of guns as a kid, listened to loud music.

So it's impaired.

So we measured all of my organs and said, like, here's my baseline.

And then we got to work, like doing therapies and measurement.

And so I became the most measured person in human history.

There's more data on my body than any human's ever lived.

And so in doing that, we just found out like what kills the body?

You know, like do microplastics harm the body?

If so, how?

You know, does going into fast food, like aerosolized, does that?

Like social media.

And so when you, it really resonates when you say you go home, like you don't know why you feel like shit.
