Now You Are Smarter

It's Friday. I seem to be suffering from a sudden onset of ADD so I thought I'd spread the love. I have no idea how many of these are actually true, but if you can verify any of them, I'd love to know.

If you yelled for 8 years, 7 months and 6 days you would have produced enough sound energy to heat one cup of coffee.

The human heart creates enough pressure when it pumps out to the body to squirt blood 30 feet.

A cockroach will live nine days without its head before it starves to death. (Creepy.)

Banging your head against a wall uses 150 calories a hour.

The male praying mantis cannot copulate while its head is attached to its body. The female initiates sex by ripping the male's head off.
(Honey, I'm home. What the...?!)

The flea can jump 350 times its body length. It's like a human jumping the length of a football field.

The catfish has over 27,000 taste buds.
(What could be so tasty on the bottom of a pond?)

Some lions mate over 50 times a day.

Butterflies taste with their feet.

The strongest muscle in the body is the tongue.

Right-handed people live, on average, nine years longer than left-handed people.
(If you're ambidextrous, do you split the difference?)

Elephants are the only animals that cannot jump.
(Okay, so that would be a good thing.)

A cat's urine glows under a black light.
(I wonder who was paid to figure that out?)

An ostrich's eye is bigger than its brain.
(I know some people like that.)

Starfish have no brains.
(I know some people like that too.)

Polar bears are left-handed.
(If they switch, they'll live a lot longer.)
