For months, the question bugging Olympic athletes hasn’t been about what they’re doing on the field or track, or in the pool or gym, in preparation of this summer’s Olympic Games in Rio de Janeiro. It’s whether they’re going to attend the Brazil-hosted Games at all. There is good reason, too. With the mosquito-spread Zika sweeping across the Americas, spending two weeks near the epicenter of the virus probably doesn’t sound too appealing. But, hey, it is the Olympics. Which is why athletes are doing what they must to ensure their health and the health of their family members — current and future, apparently. Worried about the potential effects of the virus, Britain’s Greg Rutherford is taking an unorthodox measure in that regard. He will be freezing a sample of his sperm before traveling to Brazil.
