Aging is the process of growing older. Over time, many parts of your body, like your skin and muscles, will change and get weaker.This can also happen with your memory, which is like an invisible file cabinet inside your head that helps you remember things. As you get older, it can be harder to remember things and you may forget things more often. One way to help keep your memory sharp is to practice healthy habits, like eating nutritious meals, exercising regularly, and getting enough sleep.
