What's the deal? Can people reverse the graying of their hair by reducing their stress? Can people accelerate the graying of their hair by stressing more? Likely both are true, yes. Okay.

And I think what we discovered is that hair graying, at least temporarily, is reversible. This was surprising because it goes against this notion that aging is a linear, you know, uh process that just happens over time no matter what you do. And here we should know actually a a hallmark of aging, which is you know, depigmentation, losing color and your beard and your hair. Um it's something that happens to almost everyone, but at different, you know, stages of life and and so on.

And then on the same person, and the reason we got into this was that this felt like the perfect experiment. Every hair has the same genome. They're all genetically identical twins. Right. And they're all exposed to the same exercise regime, the same food, the same stress levels.
