The more astonishing facts about the great human body are given below: –
1. Bill Brayson says “brain is the most extraordinary thing” and indeed it is, the brain can hold 200 exabytes of information which is equal to all the digital content in the world. A human brain is 75 to 80 % water other 20 per cent is proteins and fats. The information processed by the brain in 30 seconds is equal to information processed by Hubble telescope in 30 years. 20 % of our body’s energy is used by the brain and brain comprise 2% of our body weight.
2. The heart beats about 100,000 times in a day and 3.5 billion times in life Bill Brayson tells in the book. Our heart pumps out 260 litres of blood per hour and 15 per cent of blood reached to the brain. The blood takes 50 seconds to complete the journey around our body. According to calculations, the workout of our heart throughout our lifetime is equal to work carried out to lift one-tone object 150 miles up in the air.
3. Human lungs process 4,000 gallons of air per day. In a day a human being breath in and out about 20,000 times (7.3 million breaths in a year) and process 12,500-liter oxygen daily.
4. A human can grow 25 feet of hair in lifetime, eats 60 tons of food and produces 7 tons of poop.

6. The human body is made of seven billion billion billion or seven octillion atoms. The length of DNA in single-cell is around 1 meter and lifespan of DNA is tens of thousands of years. If you line up your DNA it can cover the distance from Earth to Pluto.
7. If we link human vessels together, they can cover earth globe by 2.5 times also the length of airways in lungs is 1500 miles
8. The normal human eye blinks about 14000 times in a day – means that you spend 23 minutes each day with your eyes shut.
