Trypophobia is the fear of closely-packed holes. Or more specifically, "an aversion to the sight of irregular patterns or clusters of small holes or bumps." No crumpets for them, then.

Human teeth are the only part of the body which cannot heal themselves. Teeth are coated in enamel which is not a living tissue.

You can’t visit the world’s biggest waterfall, because it’s actually deep underwater in the ocean, between Iceland and Greenland. The flow of the Denmark Strait cataract is 2,000 times more powerful than Niagara Falls.

Tomatoes are native to the Americas, so there was no such thing as tomato sauce in Italy until at least the 16th century.

The pressure in the deepest part of the ocean is over 8 tons per square inch, which is equivalent to having 50 jumbo jets piled on top of you.

All humans have an automatic dive reflex. When your face is submerged in cold water or when you hold your breath, your heart slows and your blood vessels narrow to conserve oxygen.

Golf is the only sport to have been played on the moon. In 1971, Alan Shepard hit two golf balls on the lunar surface with a makeshift 6-iron.

Sperm whales are the loudest animal on Earth at 230 decibels. (By comparison, an airplane is 150 decibels at takeoff.)

A dog’s sense of smell is so good that it can detect a teaspoon of sugar in a million gallons of water, or two Olympic-sized pools.
