Brain's Busy Hands
Why do we doodle when we are bored?

You're sitting in a meeting. Someone's talking about quarterly reports. Your hand picks up a pen, and suddenly — without even thinking about it — you're drawing spirals in the margin of your notebook. Why does your brain do this?
Here's the thing: your brain is always hungry for something to chew on. It's like a dog that needs a toy, or it'll start chewing the furniture. When you're bored, there's not enough interesting stuff coming in — the meeting is dull, the lecture is droning — so your brain starts hunting for stimulation.
