iONiUM writes: When bidding to host the 2016 Summer Olympics, Rio de Jaineiro promised the International Olympics Committee that it would eliminate 80 percent of the sewage found in the city's notoriously filthy water, and would fully regenerate the lagoon in which rowing and kayaking events will be held. Now a few months from the start of the games, Rio has given up on keeping those promises. According to an article from Deadspin, "The U.S. will send 48 rowers to Rio, and they will be as forewarned and forearmed as the federation can make them, starting with squeeze bottles of hand sanitizer that will be distributed on the flight to Brazil. Hannafin says the athletes have been asked to get hepatitis A vaccinations and polio boosters and take the oral typhoid vaccine. Their oar handles will be bleached and their boats washed inside and out after each training session or competition. Gear will be laundered at a high enough temperature to kill microbes."
