Does humor play an important role in life?

One of the most important things that there is in life is humour, because when the people are happy all the things become better.

On the one hand, I agree with the TV programs about humour because these do that you feel well for a time. Moreover these programs can help you forget your problems for one time. I believe that these programs are entertaining too.
On the other hand, I disagree with the types of humour. For example, sometimes there are some types of humour that do you don't understand alghough there are some people who think that it's funny maybe the other don't.

In conclusion, I think that humour really is very necessary for everyboody.
