Why do we laugh so little? 

There are many obstacles to laugh. We are taught from childhood that we should not laugh at certain times. Taught us that seriousness is good and the bad laugh. There are places where it is forbidden to laugh, as for example in the Church, at a funeral, during class at school and others in which it is suggested not to laugh, for example in work situations.  

One of the most important and brakes more strength to laugh when the fear of appearing frivolous or ridiculous, not to be credible, they do not consider us mature and responsible. 

For this reason, people who attach great importance to the serious mood because they fear the believe that endanger the social or economic status their hard to create.  

But what is actually dangerous rigid posture of seriousness, not the status or social position. 

So ... Laugh without guilt.
