90-95% of humans lithium deficient
Nehls estimates that 90 to 95 percent of the human population suffers from lithium deficiency, which he terms 'mental immune deficiency syndrome.'

Coastal Cultures, Blue Zones, and a Swiss Summit
At 42:00 · chapter starts 38:50
Tucker observes that coastal cultures have historically been more cosmopolitan and prosperous than inland ones, and Nehls confirms: his research shows every blue zone on Earth is a lithium-rich area. He then tells the story of a keynote he delivered at a 100-nation International Cooperation Forum in Basel — the epicenter of the European pharmaceutical industry — where he had been invited because of his book The Exhaustive Brain. He was asked to answer, in 15 minutes, what the brain needs to think peace. Organizers tried to censor his slides 5 minutes before his speech; Nehls refused to cut them. He argued that the mental immune system — essential for diplomatic thinking and peaceful conflict resolution — is destroyed by mRNA spike proteins and deficiencies of vitamin D and lithium. He closed by announcing his goal to prove lithium is an essential trace element, a declaration that landed nervously in a room funded by industries that profit from its deficiency.
All Blue Zones Are Lithium-Rich
Every major longevity blue zone in the world — Okinawa, Sardinia, and others — sits in a lithium-rich geological area. Nehls argues this is not coincidence: lithium in the water explains why these populations age well and avoid Alzheimer's.

For nicotine to have a genuine cognitive-enhancing effect rather than merely rescuing withdrawal deficit, Huberman recommends using it only once or twice per week at 3–6 mg.
Vaping = higher total nicotine than smoking
Because vaping can be done anywhere and is more palatable, people consume far more nicotine via vaping than they ever did smoking, potentially making vaping more dangerous in aggregate despite being safer per puff.

Huberman reported that on nights he used the peptide pinealon, he achieved 2.5 to 3 hours of REM sleep inside 6 hours — an unusually high proportion normally only found in the final hours of longer sleep.
