And then maybe that's like immune.

I think it's a marker of energetic stress.

The heart is calling out for help and trying to kind of

calm down the rest of the system, right?

And by signaling onto the brain.

Turns out many more people developed heart failure and like adverse events under the drug.

So they stopped the trial.

Yes.

There's a lot of beautiful things.

Likely both are true, yes.

Okay.

And I think what we discovered is that hair graying, at least temporarily, is reversible.

And this was surprising because it goes against this notion that aging is a linear process that just happens over time no matter what you do.

And here we should know, actually, a hallmark of aging, which is depigmentation, losing color in your beard and your hair.

It's something that happens to almost everyone, but at different stages of life and so on.

And then on the same person, and the reason we got into this was that this felt like the perfect experiment.
