This has been an Olympics of questions: Will everyone who goes to Rio get Zika? Can they survive the polluted water — or the polluted air? Will criminals ruin the games? Are Rio and its venues chaotic? And what is up with that green water?
Those are some of the questions I was asked by friends, colleagues and NPR's audience after I got to Rio. Several times, I gave a joking answer that was only half-joking: that the Rio Olympics are like a three-week Mentos commercial.
