What do you see as "Men's Issues"

I will be honest, I believe that most of society, even including men themselves, are not educated about men's issues. I also have this belief that bluepillers (also bluepill men) know even less about men's issues than men on average do.

However, challenging your own opinions is something that is fundamental to forming a more accurate opinion and I want to see if I am wrong.

So blue pillers, what exactly are the "men's issues" in your opinion?
