Does humor play an important role in life?

In my opinion humor is very important in our lives  for many reasons.
First of all it makes people happy and normally people like to be happy, so we can say that they like humor.
Another fact is that we can use it always (excepting some delicated situations)  to make anything happier and enjoy it more.Foe example, if you are in a boaring class of a boaring subject and the teacher starts to use humor is the exlanaition, I'm sure hat you will pay more atention than if the teacher keeps doing a boaring class. And this is just an example betwen many others.
In summary we can say that humor plays an important role in our lives beause it makes all funnier and helps us to be happy and not be depressed.
