Blue eyes are blue because the eye contains a dark protein called melanin. The amount of melanin in your body determines whether you have light or dark colored eyes.

The largest human organ is the skin. It covers and protects everything inside the body, much like an umbrella.

There are 60,000 miles of blood vessels in the average adult body. That’s enough to wrap around the world twice.

At least five senses are necessary for survival – taste, touch, smell, sight and hearing – but there could actually be up to 24 different senses . These include senses such as balance and pain perception. For example, people with diabetes often lose their sense of pain which can result in serious injuries that go unnoticed until it’s too late.

On average, a person will breathe out 1 liter of air every minute . The amount varies depending on the state of activity, during strenuous exercise, for example, breathing can increase to as much as 20 liters per minute.

Every human body contains around 10 trillion cells . In most cases they all contain 46 chromosomes from each parent, 23 from the mother and 23 from the father.

The normal pulse for adults is somewhere between 60 and 100 beats per minute, but it may be different for you since everyone usually has a resting heart rate that falls within a unique range based on their age and physical condition.

The human brain can produce enough energy to power a low watt light bulb . It requires an average of 20 watts to function correctly, which is about as much as a microwave or a refrigerator.

Although there are just five senses, humans have the ability to sense 500 different tastes , according to recent studies. The first taste buds developed in the mouth around 150 million years ago and were used to detect poisons. Today taste buds still work pretty much the same way by identifying molecules that make up what we know as taste.

Humans produce an estimated 260 million new red blood cells each second (660 per second in an average lifetime). Millions of them die every moment too because the body constantly replaces old cells with new ones.

There are more bacteria in the mouth than there are people living in the world .

The tips of each finger and toe contain 667 sweat glands, which is why they’re so good at helping us maintain our body temperatures. If you’ve ever wondered why your fingers get wrinkly after spending too much time in water, it has to do with how the moisture causes the skin cells on the fingertips to swell up.

It may not be obvious because everyone’s face is different, but all male faces and female faces fit into 10 basic shapes according to pioneering research conducted by Dr. Stephen Marquardt, an American plastic surgeon who developed a technique for creating perfectly symmetrical faces based on geometric principles.
