We all need a daily laugh. It's funny the laughter does not even need to be real. According to a study, the body does not really care whether we are really happy or not. It reads every giggle the same way and it sends a signal to the immune system to function better. So it really won't hurt to force a laughter once in a while no matter how upsetting our daily situation might be. If we will not do this, we can get sick for real because loneliness can really weaken our body for real.
