Do you want to keep your brain active and your memory strong? Here are some useful ways:

Choose the Brain Food

A proper diet will help keep your mind running strong all day long. Make sure to include plenty of fruits and green vegetables. Some of the best foods include: blueberries, blackberries, fish and fish oil, eggs, strawberries and so on.

Exercise

Get your body moving and your memory will soon follow. Exercise improves the heart’s blood flow. This, in turn, helps the brain function better and stay sharper.

Pick up a Book

The key to keeping your memory quick is to continue to challenge it. Try to always have a book in hand. After you’ve done reading a section or two, question and review the material you’ve read. Try to imagine what you’re reading. Discuss what you’ve read, and talk about it with friends or join a book club.

Develop Interest

We remember new things because we enjoy them. Find ways to make a boring subject fun by connecting it to something you already know. You can use your imagination and create a fun story behind a subject to help make it easier to remember.

Repeat after Me

When learning new information, the more you repeat it, the more likely you will be able to remember that information. Practice is the key to lasting memory.

Share with Others

Don’t keep your knowledge stored up. Teaching others is another great way to improve memory skills. Don’t be afraid of taking on new challenges. After learning something, it’s necessary to put the new information to use.
