How dirty is the water in Rio? Dirty enough that Olympic sailors are considering wearing plastic coveralls and surgical masks. One already got MRSA. With months to go until the Games, water tests are giving the worst possible news: The Rio waters are more widely contaminated by sewage than previously known.

The unseasonably warm temperatures this fall and throughout December and the early part of January were good for jokes, like a Facebook meme reading, "Go home, weather, you're drunk." Unfortunately, the weather isn't getting laughs from planners of winter sports events, who are scrambling to find venues with snow. Any snow.

Winter sports events aren't the only ones suffering from up-and-down temperatures. It's people reaching for Kleenez and Comtrex - and who are cancelling out of sports events they were supposed to participate in. A slight spike in Influenza A is being reported by the CDC, and sports provide a perfect breeding ground.

Take the eye in the sky, throw in the competitive instinct and you have the newest sport around. FPV (First Person View) drone racing uses pilots on the ground with video glasses, allowing them to see the race course as they pilot their UAVs at speeds up to 70 mph. And sports commissions better be ready.

Mention the marketability of female athletes and conversation pounces on the U.S. Women's Soccer Team.

And her meteoric rise brings the hope for reflective growth in women's tennis as a whole.
