A year of walking grew the memory center of the brain
Adults who walked 40 minutes three times a week for a year grew their hippocampus, the brain's memory hub, by about 2 percent, effectively reversing one to two years of age-related shrinkage. The control group kept shrinking. Exercise is not just for the body; it is maintenance for the mind.
This is a short takeaway in our own words, not a reproduction of the study. For the method, the sample and the caveats, read the original. Mind lives inside the Booking Minds app under the brain icon, where you can save and share each piece.
