We’re brought up to think we’ll enter middle age and it will be kind of gloomy. But as scientists look at real people, they find out the contrary. One study of men found that well-being peaked at age 65. Over and over they find that middle age, instead of being a time of depression and decline, is actually a time of being more optimistic overall.
So what kinds of things does a middle-aged brain do better than a younger brain?
Inductive reasoning and problem solving — the logical use of your brain and actually getting to solutions. We get the gist of an argument better. We’re better at sizing up a situation and reaching a creative solution. They found social expertise peaks in middle age. That’s basically sorting out the world: are you a good guy or a bad guy? Harvard has studied how people make financial judgments. It peaks, and we get the best at it in middle age.
Exercise is the best studied thing you can do to your brain. It increases brain volume, produces new baby brain cells in grownup brains. Even when our muscles contract, it produces growth chemicals. Using your body can help your brain.
