Do not Force your Brain to Memorize

I'm not memorize the parts of the brain, cell number and details. All I know was just put on, but let's head as a weight when the road not flying, the brain is also using that for a bit to memorize, a lot of thinking and understanding .. Understanding is more important than memorizing .. Memorized will be much faster even remember to understand ..

I have a short story:
One day, Albert Einstein visited by Journalists to be interviewed about anything.
At the end of the interview the reporter asked Einstein's telephone number.
Einstein did not directly answer, but he took a small notebook and then search for his name.
Reporters Amazed were the resource persons and asked, "Why you do not Memorize it?".
Einstein replied with simply, "Why Should I Memorize it if I can note it."
