YOU: The Owner's Manual : An Insider's Guide to the Body that Will Make You Healthier and Younger

When I was 14 or 15, I was going down a hill very fast on my skateboard. The I fell and hit my head on the street. I have no memory of the event, or of anything that happened for an hour or two before I was knocked out. I broke my nose, lost teeth, cut my chin open, and woke up in the ambulance shaking and covered in blood. I had to stay in the hospital for a couple of days while they ran tests.

Fortunately, the doctors didn't find any brain damage. But lately, I've been reading articles that say a blow to the head when you are young can result in Parkinson's Disease when you get older. That's the main reason I bought YOU: The Owner's Manual. Each chapter explains how a different organ or system in your bodies works, and what you can do to keep it in good shape and prevent diseases. The writing is a little corny, but I love the approach: looking at your body as a complex machine and telling you what you need to do (and why) to keep it in top running condition. Link
