Teaching others goes a long way in helping improve your memory. This means you should talk to others about the exact thing that you are trying not to forget. It reinforces it in your mind, and makes it harder to forget.
Challenging your memory and mind on a regular basis is the best way to keep it functioning optimally. Keeping your brain active through games will help to enhance your memory. Even changing your daily routine once in a while can prevent atrophy of the brain. Pick up a new musical instrument, or try a new hobby. Memory will be enhanced the more you activate those brain cells.
You can improve your memory by working out. The more fit you are, the better you will be able to remember and process facts. Also, exercising gets oxygen to the brain, and can reduce memory loss. Exercise activates brain chemicals which assist in protecting brain cells.
