How to keep healthy and be happy
  Who wouldn’t want to know how to be joyful and enjoy good health?
  Try to follow the food pyramid(金字塔). Eat a lot of fresh fruits or vegetables, some whole grains and fiber, a little bit of dairy, a little bit of meat, and very little sugar and fat.
  To exercise you can run, do sit-ups, push-ups, etc., lift weights, walk around your neighborhood.
  It is best to get at least seven hours of sleep a day because lack of sleep can harm your health. To form a regular sleep habit, go to bed at the same time each night and wake up at the same time each morning. It may seem hard at first, but it will get easier after you’ve done it for a while.
Keep yourself busy. This is good because it prevents you from having bad habits, such as smoking and taking drugs. It is also important to keep busy with positive tasks.   To keep yourself busy you can work around the house, spend time with your pets. Write in a journal, do a sport, or spend time doing a hobby you enjoy.
