1． （72）Focus on the future．．
People who regularly made plans and looked forward to upcoming events had a 50 percent
reduced chance of Alzheimer's disease （早老性痴呆症），according to a recent study．（73）But don't worry if your schedule isn't filled with life-changing events．．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．
