People often compare the brain to a computer, but the brain doesn’t have USB slots that allow you to pick up new information by jamming a flash drive in your ear.
That would be convenient, if a little painful.

You might imagine human memory is a bit like a Santa’s sack filled with life events, song lyrics and the first half of jokes.
But in truth, “memory” is not one single solid thing.
It is a term covering lots of types of recollections that are surprisingly distinct, and used constantly in different combinations by a typical human.
