A good laugh and a long sleep are the two best cures for almost anything.

Don't believe me? Give it a try.

1. Neurotransmitters called endorphins are released when you smile.
2. Endorphins make us feel happier and less stressed.
3. While the release of endorphins is increased, the stress hormone cortisol is reduced.
4. Laughing expands the lungs, stretches the muscles in the body and stimulates homeostasis.
5. A good laugh can be an effective way to release emotions.
6. Smiling is an attractive expression, which is more likely to draw people to you rather than push them away.
7. A happy, positive expression will serve you well in life.
