Reviewed in the United States on January 21, 2020
Ben Greenfield brings what seems like every inch of knowledge he has into this gigantic, heavy ass, monster of a book. An encyclopedia for every ounce of knowledge you’d want on creating the ultimate 1-2-3 combo of mind, body & spirit. These pages are life-changing for even the most advanced “biohacker.” I can’t put it down, although I need to so that I can digest the oodles of notes I’ve jotted thus far. Can’t recommend Boundless enough.
