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. The one reporter who has been feasted on by almost every mozzie in South America is still in good health.

At first he thought she'd taken his heart, but soon discovered she'd actually stolen his cellphone.COLOUR QUESTION: Do you know that none of South Africa's stars at the Rio Games - or any Olympics or Commonwealth Games - earn national colours? "You only earn Protea colours for the highest level competition [in your individual sport]," says South African Olympic Committee CEO Tubby Reddy, the chef de mission here.If that's the case, Sascoc should consider changing the colours of all its multi-sport teams from green and gold to something more colourful, perhaps the red, white and blue in the South African flag.OPENING GAMBIT: The best opening ceremony attire worn by South African athletes remains that from the 1998 Commonwealth Games in Kuala Lumpur.They formed a moving South African flag.
