No missnemesis - Man Flu is a recognised condition, often leading to pneumonia with bronchial complications. the only treatment is a pronbe position within easy reach of the TV remore, and hopefully some snacks interspersed with drinks and meals at regular intervals - should last no more than a week to ten days.
Woman Flu is a different condition entirely - characterised by a sniffle and occasional sneezing, and best treated by completing all washing and ironing, and cooking the other half a nice meal.
