Fun Fact

Laughter is not only a social bonding mechanism but also has significant health benefits. It can increase pain tolerance, boost the immune system, and reduce stress by lowering levels of cortisol in the body. Interestingly, the body cannot differentiate between genuine and forced laughter, meaning even if you start laughing as an exercise, you can still reap the health benefits!
