It's that glorious time of year when you can barely get through the journey to work without someone sneezing on and being struck down with the dreaded "man flu".
The term has got a rough ride recently with wives and girlfriends quick to point out that being full of snot isn't any worse just because you're a bloke.
Well, it turns out you might have been onto something all along as new research from Holloway University of London has found that some diseases have evolved to be more harmful to men.
The study found that viruses including tuberculosis, papillomavirus, and others all effected men more severely. Compared to women, men were 1.5 times more likely to die of tuberculosis, twice more likely to develop Hodgkin's lymphoma and five times more likely to develop cancer if infected with the papillomavirus.
Study author Francesco Ubeda explained, "Viruses may be evolving to be less dangerous to women, looking to preserve the female population.The virus wants to be passed from mother to child, either through breastfeeding, or just through giving birth."
Rather than differences in our immune system or biology, the research pointed to it being the virus itself that stops women from becoming so ill in order to continue their reproductive capabilities.
Vincent Jansen professor of Biological Sciences at RHUL commented, "It has already been established that men and women react to illness differently, but evidence shows that viruses themselves have evolved to affect the sexes differently."
Be sure to print out these findings for next time you're getting zero sympathy for that runny nose.
