Hi, I thought you may like this Mentalrobics exercise from Braingle.com:
-----------------
Focus

As we age, our thinking slows down. This reduces our ability to processes large amounts of information and transfer it into long-term memory [ For more on 'long-term memory' go here: http://www.braingle.com/mind/113.html ]. This is one reason why it becomes more difficult to remember things as we get older.

One way to improve your memory is to focus your attention on one thing at a time. This reduces the amount of information that needs to be processed by your brain which allows it to process it more effectively. Focusing your attention [ For more on 'attention' go here: http://www.braingle.com/mind/393.html ] on something doesn't have to be difficult. Turning off the television in the background and minimizing interruptions are easy steps. If you are having a conversation with someone, look at them when they talk and try to repeat what they said if it was important. Try to finish one task before you begin another one.
