Uhh, I once found good information on why that is:
Testosterone raises the pain threshold, so men are usually more resistant to pain and more prone to “tough it out”. But Testosterone also makes people more vulnerable to typical cold and flu symptoms.
So while men do have a higher pain tolerance than non-pregnant women (pregnancy hormones really hit different) they also suffer more severe symptoms.
There is anti-americanism (which I’ll gladly join in on) and then there’s making asshole memes.
