So women should stop complaning about man flu after all. Its true. We men do suffer from it because we are so fecund and virile and really damned exciting to live with......apparently.
Man flu is no myth as scientists prove men suffer more from disease.
"The reason is that they [men] invest more energy in maintaining the ability to reproduce while ill and also take the view they will be reinfected quickly so do not need to have such a strong immune system.
Dr Olivier Restif, of the University of Cambridge, said: "In many cases, males tend to be more prone to get infected or less able to clear infection.
"Proposed mechanisms include interference between male hormones and immunity, as well as risk-taking behaviour.
Men compete more with each other than females do, because of the male strategy to "live hard, die young' which means they may invest less in immunity."
