When is it okay for a guy to cry?

I am now 64 years old and during that time a lot of old attitudes have changed about these things. I was born not long after WW2 and in those days it was definitely not OK under any circumstances for a man to cry. As a mater of fact even male children were ridiculed for crying when they hurt them selves. My parents went through WW2 in a Japanese POW camp, many of their fellow prisoners were killed starved to death were worked to death or died of disease while they were there. It is interesting to note that the women were best at getting over the ordeal psychologically and that is because women are free to discus what upsets them and to cry about things when they feel the need. many of the people that went through these ordeals including soldiers that were forced to inflict fear and damage on the enemy found that even many years later their minds were in turmoil, They are finding now that crying is one of the ways that the mind deals with the negative emotions that are created under these situations, emotions that even effect the structure and the chemical balances that control the workings of our minds. The rules regarding these things are made by leaders in whose interest it is to discourage people experiencing human emotion or more to the point seeing that others may suffer the same emotional turmoil as they do. This whole issue is a very deep and complex one that is more likely to come under scrutiny in a free and well educated society then one where war or the turmoil of poverty and political control exist. This is probably why the people of the western world are beginning to explore this issue. Because of my conditioning as a child I am not comfortable when men cry never the les I realise that I have no sensible reason for feeling that way some times I wish I could.
