One of the best method towards improving my memory which I have experienced in life is in "good meditation/review."
As we get older we don’t meditate/review enough. The average person will only remember about 18% of information just 28 days after studying it. That is why it’s important to go over information that is stored in your memory in order to keep it fresh in your mind. If you haven’t thought about someone in years you can’t be expected to recall information about them instantly. We have to review our memories to keep them alive. No matter how many times you learn something, you will have to start over from the beginning if you let yourself forget it. Review your memories over longer and longer periods of time and keep them ‘alive’.
