Easy Ways to Keep Your Brain Sharp
Everyone is forgetful, but as we age, we start to feel like our brains are slowing down a bit and that can be a very annoying thing.   小題1:   Read on for some techniques worth trying. 
1.    小題2:     
People who regularly made plans and looked forward to upcoming events had a 50 percent reduced chance of Alzheimer’s disease (早老性癡呆癥), according to a recent study.   小題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.
2. Go for a walk.
Mildly raised glucose (葡萄糖) levels can harm the area of the brain that helps you form memories and physical activity can help get blood glucose down to normal levels. In fact, exercise produces chemicals that are good for your brain.   小題4:  
3. Learn something new.
Take a Spanish class online, join a drawing club, or learn to play cards. A study found that mental stimulation (刺激) limits the weakening effects of aging on memory and the mind. But the best thing for your brain is when you learn something new and are physically active at the same time.   小題5:   Or go dancing with your friends.
A．Focus on the future.
B．This can be especially harmful to the aged.
C．It should be something like learning gardening.
D．So take a few minutes each day to do some reading.
E. But don’t worry if your schedule isn’t filled with life-changing events.
F. Luckily, research shows there is a lot you can do to avoid those moments.
G. In other words, when you take care of your body, you take care of your brain
