Episode notes

Elephants have almost no REM sleep. They do have a little bit of REM once in a while, but otherwise they don't. Wonder if there are other animals with terrible night vision that might experience a decent percentage of their sleep is REM sleep. But it's a fascinating hypothesis, right? I mean, super fascinating. It simplifies the whole thing and demystifies it, if true.

This episode is also brought to you by Athletic Greens. I get asked all the time, “If you could use only one supplement, what would it be?” My answer is usually AG1 by Athletic Greens, my all-in-one nutritional insurance. I recommended it in The 4-Hour Body in 2010 and did not get paid to do so. I do my best with nutrient-dense meals, of course, but AG1 further covers my bases with vitamins, minerals, and whole-food-sourced micronutrients that support gut health and the immune system.

Right now, Athletic Greens is offering you their Vitamin D Liquid Formula free with your first subscription purchase—a vital nutrient for a strong immune system and strong bones.
