I just pre-ordered my copy of The Bulletproof Diet Book!!! If you do, you get a coupon for 10% off everything on his website, except Tech, and access some exclusive videos and updated Bulletproof Diet Road Map and a cheat sheet on how to hack your sleep, like killing all sources of blue light (or wearing red lenses at night) and taking a Magnesium supplement, or bathing in Epsom Salt (Magnesium Sulfate), before bed.
Stay well engineered,
Devon
