Be it a slew of good jokes, a slapstick comedy or laughing yoga, find something to give you a good hearty laugh that brings tears to the eyes or a giggle fit that makes the sides of your body ache. People are 30 times more likely to laugh in groups than alone and, not surprisingly, laughter is associated with helping to develop person-to-person connections through a feedback loop characterized by laughter, social bonding and more laughter. Laughter, like so many other endorphin-triggers, helps to reduce certain stress hormones and, while it might be contagious, it strengthens your immune system rather than weakening it.
