Your eye muscles move 100,000 times a day.

You get taller in space.
NASA verifies that astronauts increase 7.5 cm due to micro-gravity  To some degree, a similar stretching of the spine happens to you every night. When you lie down, gravity isn't pushing down on your vertebrae, so you might be 1 cm taller before you wake up.







There are more chickens than humans on earth.

A sneeze can travel at 65 km/h.
The reason why sneezes are so powerful is because not just the nose is involved. It is a
reflex response that involves the sudden contraction of muscles of the abdomen, chest, diaphragm, throat and face. Have you ever noticed that you have to close your eyes when you sneeze? This is because the muscles that close your eyes are part of the reflex response as well.

Your body contains enough carbon to fill 9,000 pencils
Most of the human body is made up of water, with cells consisting of 65-90% water by weight. Therefore, it isn't surprising that most of a human body's mass is oxygen. Carbon, the basic unit for organic molecules, comes in second. 99% of the mass of the human body is made up of just six elements: Oxygen (65%) Carbon (18%) Hydrogen (10%) Nitrogen (3%) Calcium (1.5%) Phosphorus (1.0%). So, a 70 kg adult contains 13kg carbon. If we assume a pencil has about 1.5g of graphite in it; that’s close to 9000 pencils.

Cat pee glows under black light

A blue whale's heart is the size of a car

Blue whales grow to be an average of 25m long and weigh about 10,000kg. The largest of the blue whales (136,000kg) has a heart that weighs about 450kg and has 6,400kg of blood circulating in its body. The heart is about the size of a Volkswagon bug car.
