So as, let's say, a six-year-old, we all wanted to be awake with the adults at the weekend and try to stay awake. And we would try and try. But, you know, I just remember at nine o'clock being kind of like lifted up to bed because I'd fallen asleep. It used to annoy the living daylights out of me.

So there, even though I'm mostly a neutral, I'm kind of like an 11 to 7.30 kind of guy, there, I still had my neutral chronotype. But as a child, my neutral chronotype was sort of 9 to 6 a.m. in the morning. And then as I got older, I moved forward in time and I found my adult sweet spot.

But then per your question, as you get older in late life, now you start to regress back and you become more childlike. You want to go to bed earlier and wake up earlier. It's the reason that if you go to Florida, you know, when you've got a lot of retirees, you've got the early bird special where people now are eating at 4.30.

You know, they finish their meal, they're home by eight and they're in bed by nine because they've regressed. But even if you take, you know, 180-year-olds in Florida, you'll still get a distribution of some people wanting to go to bed at, you know, 8.30 p.m., others more close to 10 p.m. There's still the variability of morning types and evening types.

It's just that where that morningness and eveningness sits on the 24-hour clock face gets dragged around across the lifespan. I know that's a complicated way, but does that make some sense? Absolutely. Yeah, it makes complete sense.

You might have heard me say that I took my testosterone level from 495 to 1006 last year. And one of the supplements I used throughout that was Tonkat Ali. I first heard Dr. Andrew Huberman talk about the really impressive effects that tons of research was showing, which sounds great until you realize that most supplements don't actually contain what they're advertising. Momentous.
