For this installment, Canterbury has collaborated with Jason A. Hunt, a guy who has received extensive medical training and is also a medical instructor. And while neither of these men are MDs, that’s not a deal-breaker for me. First aid isn’t brain surgery, and many doctors have a hard time communicating with laymen in an understandable way (particularly through books). We don’t need to know the name of every bone and muscle, or every single chemical process in the body. We just need to know how to keep the red stuff in and keep the patient breathing.
