Dave Asprey is a fascinating guy. He’s a professional bio-hacking machine whose publicly-stated goal is to live to 180. We covered his last book called The Bulletproof Diet and our kitchen’s pantry is filled with a bunch of his Bulletproof products. In this book, he unveils his best bio-hacks for, as the sub-title suggests, “activating untapped brain energy to work smarter and think faster.” Big Ideas we explore: Your brain on energy, kryptonite dust (what’re yours?), mitochondria (one QUADRILLION!), EZ water (how to drop into that spot between a gas and a liquid), and junk light.
