046 - Concussions and the Canadian Food Guide

Football player facing off with a rhinoceros

 

Chris gets surprisingly aggressive (and hairy) during a football match, which leads the boys to discuss concussions. Jacob goes to a hockey game and finds a lot of people who are intimately familiar with mild traumatic brain injuries. How common are they, what's the treatment for them, and should you let someone with a concussion fall asleep? Perhaps more importantly, would you let your kid play football (or hockey)? Also: a new iteration of the Canadian Food Guide gets rid of food groups; talcum powder strikes back; probiotics make surprising appearances in our food supply if we are to believe Canadians; and a joke few people will get. It's Skeptics with a-wait, wrong show.
