I'm sorry, but I don't accept this at all.
I'm sure mythbusters say they proved it, but they could hardly do anything else.
Pain is subjective. I know, when I've had tooth ache, for example, that I can control the pain better, by focusing upon it. It's still there, but under some control. Pain exists to tell us something is wrong. Not to remind us who suffers more.
There's a series of adverts on British TV at the moment for a large chain of chemists. In between features on womens' vitimins, womens' foot spas, cosmetics and such, there is a scene where two women, both obviously suffering from heavy colds, talk about how their husbands are at home, suffering so badly from colds. The message, that women have to suffer while the men put their feet up.
The point is, these adverts are aimed at women, to get women to spend their money on their stores. Basically say, you suffer so much, come and spend your money here and feel better.
Sorry, it's all crap. If you like to think in messages, those adverts are saying women deserve to suffer. They don't.
There are other adverts that claim that women are so much more sensitive so they deserve to wear nicer, more gentle clothing. (Come to this store, with your money, and buy it). So, depending upon who is trying to get your money, the messages are different.
