Why do I forget some things and remember others?
Brain's Filing Trick
Why do I forget some things and remember others?

You can recite the words to a song you haven't heard in years — but you just walked into the kitchen and have absolutely no idea why. What gives? Your brain isn't broken. It's actually doing exactly what it was built to do: keeping some things and quietly letting others slip away.
Here's the secret: your brain is not trying to remember everything. If it kept every blink, every itch, every license plate you ever passed, it would be a hopeless junk drawer. So instead, your brain is a careful sorter. Most of what hits your senses gets a polite "thanks, but no thanks" and is gone in seconds.
