Memory is one of those things that falls inside of the group of use it or lose it. Aging also causes forgetfulness. But that doesn't mean you should stop practicing memory skills. As a matter of fact you need to improve your memory practice. You probably will will see more and more memory type games display on the market as the Boomers come fully into bloom.
Memory skills require practice as with all different kind of skill development or self improvement you wish to achieve. I wish there are a fairly easy button to push for this but in fact there is not. But neither is it difficult.

To increase bad memory takes slow deliberate steps and exercise daily. You can make this happen by using technology; there's plenty on the market, playing memory games, or memorizing writings.

Memory games generally use a set of small cards with symbols that you just flip upside down. As you turn them over, you try to get the corresponding card. When you do this you can or may not find the corresponding symbol. If you find a different symbol, the object is to remember the symbol and where it actually is located. If you've got a truly difficulty in remembering things you might want to start with something a little less advanced for this involves not only remembering what you see but also where it is located.
The old fashioned way of improving memory, which has apparently gone out of practice, by observing young people these days, is to memorize a favorite writing. This can be a bible verse, a poem, a motivational paragraph, a section from your favorite play or book, or even a selection from a magazine.

Your body including our brain has this very interesting method of remembering and responding to what we ask it to try and do. If you quit asking, it quits responding. An analogy is people who participate in sports. Let's use a jogger or walker for example. One day you decide you've been walking for exercise but now you'd like to jog a bit. The new you find that you can only jog a block or two. Your body will remember this the next time you ask it. You will find that it's easier to jog that two blocks and maybe you can make it one more. It's not just the muscle response; it's your brain remembering that you may ask for this activity again. This type of response happens with memory as well.

So, choose the writing. Set a goal for the day; today I will memorize five words. Tell yourself you won't stop until you have all five words. Do this every day until you can move on. You'll know it's time to move on when you remember the five words easily. Pick the next five words and add them to the first five. Repeat the instructions above. There is a limit to how much you want to ask your memory to do. As an example, everyone is not built the same. Some people have a natural ability to remember everything. Others struggle with the ability to remember anything. If you struggle, don't become frustrated if you cannot move beyond 10-30 words. Pat yourself on the back and reward yourself. You probably weren't able to perform this before and now you can. You've just exercised you memory.

Don't stop though because similar to muscle, if you stop asking, your body will stop responding. Try the learning games now. See if you can remember place and symbol. It takes some getting used to, but can actually be quite fun, especially if you have a friend to compete with.
