Research shows that laughing has significant (benefit). Last week, I was asked to go to theater with my friend. It was just a comedy in someone pretended to be someone else. The character was very thin and weak， pretended to be very strong. One day， he was boasting that he could beat anyone in the world when a strong man， tall and fat， appeared in front of him. With (embarrass) look on his face, the thin man fled away as soon as possible. The whole audience burst into laughter, relieved and relaxed.
