Our heart beats around 100,000 times every day and 30,000,000 times every month.

Our eyes can distinguish up to one million colour surfaces and take in more information than the largest telescope known to man. Our lungs inhale over two million liters of air every day, without even thinking. They are large enough to cover a tennis court.

Our hearing is so sensitive and it can distinguish between hundreds of thousands of different sounds. Our sense of touch is more refined than any device ever created.

Our brain is more complex than the most powerful computer on earth and has over 100 billion nerve cells. Human body gives birth to 100 billion red cells every day.

When we touch something, we send a message to our brain at 124 mph and a normal human being has over 600 muscles.

We exercise at least 30 muscles when we smile and human bodies are about 70 percent water. Each person produces one liter of saliva every day.

The nose is our personal air-conditioning system: It warms cold air, cools hot air and filters impurities.

In one square inch of our hand we have nine feet of blood vessels, 600 pain sensors, 9000 nerve endings, 36 heat sensors and 75 pressure sensors. We have copper, zinc, cobalt, calcium, manganese, phosphates, nickel and silicon in our bodies.
