Physical activity increases blood flow to your whole body, including your brain. This might help keep your memory sharp.

For most healthy adults, the Department of Health and Human Services recommends at least 150 minutes a week of moderate aerobic activity, such as brisk walking, or 75 minutes a week of vigorous aerobic activity, such as jogging — preferably spread throughout the week. If you don't have time for a full workout, squeeze in a few 10-minute walks throughout the day.
