Humour it is necessary to survive?

Nietzsche said '' men suffer so profoundly that they needed to invent laughter''. When you read this sentence you trend to agree with it. We have to admit that the humanity suffers sometimes we have our bad moments and one way to return the happiness in our minds is to laugh about whatever, just smile and forget our pain.

It's true that, saying that laugh is necessary to survive seems to be absurd, but not at all, because if somebody doesn't laugh at all he'll probably die earlier than another one who lives his life with a bit of positivism.
Humour is for a lot of people a job, so many comedians works hard to make us laugh. I admire these people, because in their shows they just need to inspire them in the way that people are to make us laugh. So humour it's a critic towards humanity and it foolishness.

Like I've said before humour is a self-criticism that humans invent to try to forget what miserable life they have or how they are. Because some prefer laughing then crying themselves. So it's true that people need humour to survive. because if it didn't exist, life will be boring, then it helps us to make life easier.
