There are many aspects of life that are unfair. Often these take the form of hidden rules about how the world really works that can be in conflict with the nominal rules about how it is supposed to work. 

As men, we need to be aware of these rules and they ways that some of them can put us as a disadvantage.  This is not so that we can cower in fear, but rather so that we can be smartly and strategically courageous.
