As my promise.

As my promise, I'll add few more benefits of laughter. See below:

MENTAL BENEFITS
* Relaxation. Laughing relaxes all of your muscles, releasing pent-up tension from your body. Try it after a particularly tense-filled day at work or home.
* Distraction from Pain. If you're experiencing pain, laughter can help to take your mind off your circumstances and provide some temporary relief. In fact, it can even reduce the actual pain because laughing releases endorphins that are just as effective as equivalent doses of morphine!
* Improves Thinking Skills. When you laugh, both sides of your brain are affected. This improves comprehension and your ability to learn, which suggests that kids who laugh a lot will do better in school. Engage your child in a tickling session every evening. It just may be the thing you're looking for to see your child's grades improve!
* Reduces Stress. Laughter boosts serotonin which, in turn, can ward off depression and anxiety or simply help to lift your spirits and turn around a bad mood.
So the more you laugh, the healthier you'll be and the better you'll feel. The best part is that laughter is contagious. If you have a hard time finding things to laugh about, hang around with funny people or those who you see laughing a lot throughout the day. Soon you'll find yourself laughing along and reaping the benefits that come with it.
