I've seen reports that one of the OAR athletes in curling in these Olympics (Pyeongchang 2018) might have failed a Doping test.
I really wonder... what could be the advantages of doping in curling? Curling is not a sport of power, or endurance... they rarely throw the rock full power, and even then, a little bit more or less power will probably still to the job just fine.
So why could a curler be using performance enhancing drugs?
