I’ve also touched on the importance of a sense of humor. I think this is extremely important, as important as any of the other things in life, like love and gratitude and solemnity. Humor has a healing effect among people. It points out the ambiguities in life, and it points out very often the ambiguity between the content and the context and how you sort of see the two end up really the opposite. Humor also has a way of connecting people and helping them put aside differences through a new perspective or mindset. People have written books on how they recovered from grave illnesses by just employing nothing but humor. Laughter releases endorphins in the brain and releases stress, among other major health benefits.
