Man flu is the same as a cold in a woman -runny nose, bad head, but we still wash up, clean the clothes, cook, housework........in a man it is 50 million times worse and they lie on the couch, moan that they had to work etc.!!!
My darling hubby had a cold, sorry man flu and I asked him if he would like a flu remedy from Asda while I was shopping (cos I only had a cold) and he said he thought a bottle of rum would be the best treatment!!! He drinks it in hot water with a large dash of rum - in fact a 70cl bottle only lasts for one bout of man flu.
Good luck and put your feet up pet, us women do understand !! He he he
