1. Women are much more likely than men to decide that they do not want to be in relationships ever again.
2. Women who are single tend to live longer than their married counterparts.
3. Men who are single tend to live shorter than their married counterparts.
4. Men are rather emotionally repressed in general, and tend to only truly let their face known to their girlfriends/wives.
5. Women are much more open with their emotions, and tend to show signs of depression more openly.
6. Men tend to have a higher place in society than women in terms of socioeconomic status, leading to (among other things) less depression
7. Abject failure in relationships tends to mitigate the other depression-reducing aspects of male-ness
8. Haptics (or touch) is very important for emotional well-being. For males, they are unlikely to find this from sources other than relationships, outside of demonstrative religions (at least in western societies).
9. People in said demonstrative religions tend to have lesser occurrences of depression.
Just wondering...
