I bought this book as a gift for a young man and found myself reading different sections, starting with the penis section and continuing backwards thru pancreas and nose, then to the moles and later the workout section. I found it to be informative and useful, but written casually enough to hold the 22 year old's interest. So many men are so uniformed about the functioning of their bodies. This book cracks the myths and sets straight the rumors about many areas of a man's heatlth.
Worth it's weight in gold.... buy it. Incidently, I couldn't find the parts mentioned by the one star reveiw.
