Congratulations, you’ve won the grand prize!  

Okay, just kidding.  

But if you did win the grand prize, you would probably remember it weeks, months, or even years later. Compared to, say, getting a dollar-off coupon on your next paper towel purchase. 

In the modern world, you have a firehose of sensory input coming into your system.

How does your brain decide what to remember and what to forget? 

How is it that your brain remembers the important stuff while not getting bogged down by things that don’t matter?
