Why Do Men Have Nipples?

Just finished this one last night. Very quick read in a question and answer format about stuff you'd like to know, but just never had the courage to ask your doctor (or anyone else for that matter). What is snot? Why does sweat stink? If you ate a dead person would it make you sick? You know, questions that have haunted you since the day you learned that your finger would fit into your nose! I enjoyed it (no, not my finger in my nose), but the book was over in less than 2 hours of reading and some of the answers left me wanting more information instead of being satisfied. My rating is a B.
