People who regularly made plans and looked forward to coming events had a 50 percent reduced chance of Alzheimer’ disease（早老性痴呆症）, according to a recent study. 【3】 Something as simple as setting a goal to have a weekly coffee date with a friend will do. There’s evidence that people who have a purpose in life or who are working on long or short-term goals appear to do better. In other words, keep your brain looking forward.

Take a Spanish class online, join a drawing club, or learn to play cards. A study found that the best thing for your brain is when you learn something new and are physically active at the same time. 【5】 Or go dancing with your friends.
