Theres 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.

3. Learn something new

Take a Spanish class online, join a drawing club, or learn to play cards. A study found that mental stimulation 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. 【5】
