This is a fantastic non-fiction comedy book where there are two people: one's a doctor and one's a normal civilian. The civilian one's to know answers to how much your bladder can take, what's the most fart food and all sorts of weird yet true facts. They even talk about if you held your urine for so long would you explode or how long would you exactly survive if you were skinny or fat without food, and what's special for when your heart stops.
I Would recommend this Book
I would recommend this book to 8-12 year old students. This sort of book is a mixture of non fiction, comedy, and facts (like horrible histories but a bit more gruesome!)
