Can we live without humor?

Try to imagine life without humer? Is it so difficult? I'm sure that the answer is yes. Our world is full of humor: we use it with friends, on TV shows, on advertisments etc. Probably, humans can live without humor but that's impssoble in this society. If we lived in a diferent way, may we could be without humor but now, we can't.
Humans, to live together, (families or with friends) needs to use humor. It's impossible to be with other people 24h/day and don't laugh any time. You talk with others and sometimes the conversations are lazy. As a result we use humor to do mor fun the conversations.
Besides, humor gives to live a little bit of color. Without that resuruce, live wold be similar to black and white photos: can be a great photo but it default something. I think humor and laugh are the best parameters to know if one is happy or not.
In conclution, humor is necessary for us because give us a color to this life.
