SECRETE A CORROSIVE ACID.
Yup, that’s right. Your gut contains a highly potent acid that could melt metal in an instant. Fortunately the lining in your stomach wall keeps the poisonous stuff contained, so it breaks down your lunch—not your lunchbox!


MIMIC ON CUE.
Have you ever yawned because somebody else just yawned? Or laughed because someone else just laughed? Research shows that hearing a laugh actually stimulates your brain to do the same, and that goes for yawning too.


SHED.
Just like your kitty cat, only you shed skin, not fur. Believe it or not, we shed 50,000 skin cells every minute. Globally, dead skin accounts for about a billion tonnes of dust in the atmosphere. Icky.


REWIRE.
For instance, in blind people, the brain's visual cortex is rewired to respond to stimuli received through touch and hearing, so they literally "see" the world by touch and sound.


LIGHT UP A ROOM.
And we don’t mean with that smile…. While awake, your brain generates 25 watts of power, which is enough to illuminate a light bulb.
