Can we live without humor?

Humor is one of the main important things in a human life, it's very linked with health. People without humor are very sad, and unsociable. People have to have relations with other people and without humor this relations aren't possible. People likes other people if make they laugh or if they're fine together. This is possible thanks to the humor. I think that a sad life is impossible, sad people ends badly. Live without humor should be very boring,one of the best things are laugh with friends... without humor friends shouldn't be exist neither.
In conclusion, we can life without humor, yes, but in a different way. Really it shouldn't be LIFE it should be pass the days, bored, since the death.
