“And open bodies of water aren't good. Actually, I told my friend Samer Hattar. He's the director of chronobiology unit at the National Institutes of mental health. He came on the podcast. Got him really-- he's great about all the stuff on light and sleep. Taught me a lot of that over the years. We're good friends. I told him about the cold water thing, and he got into some river in Bethesda and almost drowned. And Sam right now-- he has a story about how he almost drowned, and what he was-- and he thought about a paper he wanted to write while he was almost drowning. So just be careful-- open bodies of water, that kind of thing.”
