David Isaacson's second week at Rio Olympics Games

David Isaacson's shares his best moments of his second week at the Rio Olympics Games. NOT SO HOT: Forget the Zika virus - the ice-cold air-conditioning in several media venues and shuttle buses here has claimed more victims. Some places are so cold that well-equipped hacks have been spotted wearing jackets and scarves suited for the Arctic!At least three South African journalists were felled by heavy chest colds this past week, and none of them has been bitten by a single mosquito.
