Of all the questions surrounding reports of a Russian curler¡¯s alleged doping infraction at the Pyeongchang Olympics, the biggest is why?

Why would an athlete in one of the Winter Games¡¯ least taxing and least physically demanding sports feel it necessary to use performance-enhancing drugs?

Even curlers taking part in the Olympic competition were left scratching their heads on Monday as news circulated that Alexander Krushelnitsky, an Olympic Athlete from Russia who won a bronze medal in the mixed doubles with his wife Anastasia Bryzgalova, is suspected of testing positive for meldonium, a banned substance that increases blood flow, improves exercise capacity and is favored by endurance athletes.
