Yeah.

And you know, like when I did the live stream mushrooms, he's like, I'm in and I want to hang out with you.

And so he's just like, he's such a cool dude.

Yeah, so the idea behind this is how do you tell if somebody's in good health?

You can look at them.

What is the skin quality?

What are their muscles?

Are they aerobically fit?

It turns out that nighttime erections for men is a major marker for health.

And that if a man is not having erections at night when he's asleep,

it's representative of much larger problems in the body.

But before we did this, nobody talked about this idea.

But every night you go to bed, your body goes to a natural process of erection cycles.

So men have between three and five erections every single night.

It's not sexual.

Your body is just like pulsing the system.

Females have the same thing.

So females also have these arousal cycles that are clitoris and gorges.

So we can measure a man's erections.

So we have this little device you put on the base of the penis and you go to sleep.
