The 2018 Olympic Winter Games bring forth a stunning display of athleticism… and with it, athletes biting medals. So, why do they do that?
Historically, gold was alloyed with denser metals to make gold harder. Merchants would then bite the gold pieces to determine if they were lead forgeries (i.e., if biting a gold piece left tooth prints, it was a fake). Nowadays, it’s more for show. However, it can be a terrible dental practice. Unfortunately German luge athlete, David Müller, found this out when he chipped a tooth when biting his silver medal on the podium in the 2010 Olympics.
Moral of the story: the next time you are on the Olympic podium, resist biting your medal.
