Nowadays, people pay too much attention to seats, always think about tickets, throw the house in a mess, can't put down the shelf, can't tear their faces, take care of the children ... Everyone's face is anxious. Why not try different expressions? The "99 multiplication table" of health care suggests that you should worry less and laugh more. 4-year-olds laugh every 4 minutes, and adults should laugh every hour. Laughter can not only improve your vital capacity, but also help you lose weight and relax. Laugh 15 minutes can consume 40 calories. If you do this every day, you can lose at least 1.8 kg a year. Anyone who is out of control may wish to prepare an "emotional first aid kit", such as watching a movie, running a few laps, finding a place to eat snacks, being with children, and sharing smiles with others when queuing for shopping, so that smiles can light up life like sunshine and "warm" their hearts. ?
