EYE CARAMBA!

Three things you didn't want to know about your eyes:

1 Behind the human eyeballs, there are pads of fat which were considered delicacies by cannibals.

2 Those having corrective laser surgery for poor sight can smell their eye tissue as it is burning.

3 Each of the follicles of the lower eye-lashes consists of a tiny pool of grease which is home to one (just one) minuscule crab-like creature.
