Keeping the brain as healthy as possible might help slow the fuzzy thinking that develops with age-related brain changes. The best way to stay sharp is by living a healthy lifestyle: exercising regularly (at least 150 minutes per week of moderate-intensity exercise, like brisk walking), sleeping for seven to nine hours per night, eating a Mediterranean-style diet, managing stress, socializing, and learning new things. Doing crossword puzzles may also help sharpen cognition. So might treatment for underlying health conditions, such as depression or thyroid disease.

Pheromones, the "love chemical," are produced by many animals and insects to attract the opposite sex. It's possible that humans also may make and process pheromones through vomeronasal organs in our noses.

For example, people can keep their brains active by reading, writing, doing a hobby (such as knitting), or playing an instrument. And people can exercise while in a seated position. It's possible to do an aerobic workout that gets the heart and lungs pumping, such as a seated dance routine or calisthenics, as well as muscle-strengthening activities or stretching exercises.

A 2022 study of 78,000 healthy people (ages 40 to 79) who wore fitness trackers found that people who walked about 9,800 steps per day (about five miles) were 51% less likely to develop dementia, compared with people who didn't walk much at all.

A study found that people with mild cognitive impairment who did crossword puzzles regularly showed modest improvement in cognition and less brain shrinkage. Will doing crossword puzzles be helpful to people whose thinking and memory are normal?
