Is humour necessary in our lives?

Humour in my country is important like every where but on the street, you don't see people happy when they are walking alone and in my opinion this is sad because it means that they are not happy, they are just living. 

Firts of all, for me, humour is very important in our lives, when we are sad, just a sentence with a bit of humour it can make us happy. 

Secondly if we live without humour our life will be sad, always the same, just work and make moeny. 

 

In conclusion humor makes our lives happier and longer, without humor we would be angry every day and our face would be always sad, so jokes, humour and laughther are very important to live well.
