When there's two people living in the same house, same bed and loving on each and one gets the China flu and the other one doesn't, there's no logic behind this BS. You'll either get the China virus or you won't, my advice is to carry on you only have one life to live.
Outstanding point, his wife did not get the Kung Flu... nor his daughter or son in law or granddaughter. They all live in the same house.
