Body in numbers: interesting facts you didn't know

The average person has a height 171 cm and weighs 66.6 per kg. It is composed of 206 bones and 230 joints that support 500 separate muscles, covered 5.5 m3 skin.

Inside our body circulates about 4.7 liters of blood. With an average frequency of 72 beats per minute your heart is doing 103680 cuts a day.

Your body contains:

• lime in a bucket of lime whitewash;
• fat for seven bars of soap;
• water – for a 45-gallon barrel;
• iron – on-one five-centimeter nail;
• of phosphorus for 2,200 match heads.

You will also produce about 60 watts of power – enough to operate a regular household light bulb.

One square centimeter of your skin contains approximately 3 millions of tiny cells.

In this small area you have:

• 90 centimeters of blood vessels, providing the cells with food;
• 2 receptor, are used to determine the cold and 12 to determine the heat;
• 15 sebaceous glands, providing a softness to the skin;
• 25 receptors that enable it to sense touch;
• 100 sweat glands to remove toxins;
• 200 nerve endings to register pain.

On the head you have about 120 000 hairs; more (150 000), if the hair is light, less (90 000) – if red. They grow a little longer than 19 hours a day, while the rest are in peace. Body hair grow less time (10 – 12 hours a day).

If you are a man, you on the cheeks has 25,000 bristles that grow during the day, a quarter of a millimeter, and the entire life – is about 630 cm

Your blood flows through the blood vessels of a total length of 160,000 km, and to pass around your body, it takes about a minute.

Every second 10 million red blood cells derived from circulation, destroyed and replaced. For every extra pound of fat accounts for more than 300 km of additional blood vessels, the heart has to work harder.

Liz Gilbert: We perfect in its imperfection

The eyes consume about a quarter of the nervous energy of your body, daily registering approximately 50,000 images and transmitting them to the brain.

Whenever you blink, stop the visual perception of the world in three tenths of a second, so from 11 to 20% of the time your awake you don't see what is happening around them.

During the day, you are doing 23340 breaths. published
