Pain researchers have a joke that when someone is asked to rate their pain from 1 to 10, the most common response is 11. Dr. Jeffrey Mogil, a neuroscientist and pain researcher interested in how genetics, social factors and sex differences affect pain, believes this joke to be based in truth. Dr. Mogil heads the Pain Genetics Lab at McGill University & is the founder and Director of NAPS, the North American Pain School. This week he joins the fellas and schools them all about the science of pain and it's absolutely fascinating!
