So all of a sudden now, how does my behavior influence my recovery? And that is a major signal. Now you can hack it because you can track it. You cannot hack what you can't track. And that's one thing. And if you're saying, I don't want to do that, that's too much work. One of the cheapest biohacks of all that improves leadership and performance and longevity and aging is darkness.

What I'm talking about is get yourself some blackout curtains and put tape over every single source of any light in your bedroom. And if you have to, put a towel under the door. No light at all. Sleep in a cave. And people say, oh, but that doesn't really matter. No, it matters far more than you might imagine because your body

is desperately trying to figure out what time is it because if it's nighttime i should be recovering and if you look at the last two billion years there was never any bright light at night except for firelight and maybe lightning that was it so now you turn on your bathroom lights or you have a little blue or green or yellow or white led in the bedroom the cells in your body are going

there's light, it must be daytime, and then it doesn't do what it's supposed to do. And my evidence, a study in Japan of 800 people show that the amount of light that leaks in around your curtains from streetlights increases depression by 69%. It literally makes you old, it makes you insulin resistant. So blackout your room, you don't have to do any of the tracking, just do that.

Because now we understand why we understand the science. Blackout curtains are cheap.

there's a good chance that you might not succeed in getting her to do the TV thing. You can get the true dark glasses. True dark is a circadian biology company. I started it 10 years ago. These are the daytime glasses I'm wearing right now. The yellow ones, we make glasses for sleep that are on the true dark.com website.

And we just published in a medical journal, a study of brainwaves and 15 minutes of wearing the true dark glasses and put your brain in a state of meditation, and they trick your brain into thinking it's pitch dark, even if there's light. So even if she's got those on, you put on those glasses, you'll look a little bit like Cyclops from the X-Men.

And then your brain will know it's dark, even if the TV is on. And that is a massive thing. It's what I do in hotel rooms where there's always bad lighting.
