I have only read the first two chapters but have to say it is the funniest book I have ever read! I usually bring the book with me to the gym to read while I am on the elliptical or treadmill. I laugh so much while reading the book, that people come up to me to ask me what I'm reading.
The book teaches you about healthy living but also the crazy ways people work towards creating bodily perfection. For example in the first two chapters I learned about the caveman (Paleo) movement where people live like and work out as cavemen lived. I also learned about the calorie restriction movement where people believe if you live on the edge of starvation you will increase your lifespan!
