Did you know that laughter can reduce stress in practically every human organ … that humor can boost our immune system and fight viruses? A little laughter and wit make everything tolerable—even a ding letter, look of rejection, an empty inbox, snide remark, or spotting your group of so-called friends hanging out at your favorite restaurant without you. Humor cultivates optimism, an attitude that protects you from negativity, fear, and panic. In fact, it’s pretty hard to laugh and cry at the same time, even though they look very similar. And unlike exercise and eating broccoli, laughing is fun. “Time spent laughing is time spent with the gods,” says a Japanese proverb.
