Unabridged Audiobook
Great book about many different ways to biohack. There was a good mix of free/low cost things as well as some spendy items, some low/no-tech ways and some high tech ways, some ancient methods and some brand new. This book is good for someone unfamiliar with biohacking or moderately knowledgeable. I follow the GoodReads rating system (3=good, 5=phenomenal life-changing) not the Amazon one (only 5 is acceptable.)
