Because when your mitochondria are not functioning well, if they're damaged, if they're unhealthy, they will...

They are the major generator of reactive oxygen species.

And so, you know, that's another sort of surrogate marker, I would say, as well.

But yeah, it's kind of annoying that we don't have a direct marker of mitochondrial function.

And I know people are working on that.

But, you know, everything takes a long time to make its way to our homes.

I mean, the biohackers out there want to know, right?

And we were talking about this urolithin A compound on the drive up here and how that's important for mitochondrial health.

And we're actually going to cover it in the newsletter.

But I'm taking it right now.

And I'm like, it's all, what am I measuring to know if it's really doing anything, right?

I guess VO2 max would be something to measure.

But you have to have good baselines.

And I don't have all that.

So, you know.

Okay.

Well, I want to circle back to sheer stress because that also plays a role in some of the mechanisms behind the reduction in cancer mortality as well.

And that's something that Dr. Carrie Carnier talked about on the podcast.

So, you know, the reductions in...
