As soon as you hit your 20th year, your brain cells slowly begin to dwindle in number. Not only that, they also receive lesser chemical supply in order to function smoothly. Aging does mess up with your brains because the older you get, the more these changes will affect you. It will make storing information more difficult than usual, hence, you may suffer from
memory loss. But don't worry because short-term and remote memories may not be affected at all although your recent memory may fail in remembering names or data you've accumulated lately. But if there's any consolation at all, this is a normal occurence of aging.
