intestine Perhaps you've heard of a heart transplant, a lung transplant, and even a uterus transplant, but have you ever heard of not just a bowel transplant (WARNING: STOP READING NOW IF YOU'RE EASILY DISGUSTED), but a feces transplant? Yes, it's true, people sometimes transplant poo. I learned this from What's Your Poo Telling You?, a fun-loving and fact-filled book all about bodily excretions. Folks with really bad cases of colitis caused by poor intestinal flora can sometimes benefit from a squirt of someone else's nicely populated bacterial colony. As the book points out, this last-resort treatment may have a bright future "owing to the short list of willing recipients and the potentially endless supply of donors."
