Like they say, only 10%

...is how much we typically use of our brain. You know why? Cuz using anymore than that really hurts. Really. You know how when you think too much, you want to stick your head in the sand somewhere to make it stop? (Well I don't know about you, but I do.) Yeah, that's probably a sign you're exceeding the allocated 10%.

We're only human. We set our limitations, then we blame science.
