What's the mechanism there?

That's crazy.

And is there a link between our hormone levels, things like my testosterone levels, and the nitric oxide?

Got you.

So taking testosterone or estrogen therapies helps to increase mononitric oxide levels.

And there's a two-way relationship as well with exercise then, because I've read in your book that exercise activates and stimulates nitric oxide production, but you also just told me that if you want to get the great benefits of exercise, you need nitric oxide in the first place, because else your blood cells are going to be very narrowed

less oxygen traveling through you.

You're going to do a worse workout as well, presumably.

When I think about the role that food plays in my nitric oxide production, what should I be eating to increase my nitric oxide levels or to keep them at a healthy level?

And it lowers nitric oxide production.

Just a bit of a tangent there.

You mentioned that's why they have open wounds that don't heal.

Okay, so nitric oxide's playing a healing role in wounds and scars?

Absolutely.

So I've got this scar on my head.

I was playing football the other day.
