1. Did you know Camels’ humps are not for water storage?

Camels can drink 113L of water in 14 minutes. The water will be stored in their bloodstream and not in their humps. Humps store fat that provides nourishment when food is scanty.

2. Our weight on Earth varies from our weight on the moon.

When moon gravity is compared to Earth’s gravity, moon gravity is only a 6th of someone who weighs 68kg on Earth. He or she will weigh 11kg. The main reason why moon gravity is low is that moon mass is one percent the mass of Earth. The weight of objects on different planets varies. For example, on Jupiter, it will be much more compared to other planets.

3. The body of an adult is made up of 206 bones.

Our body skeleton is made up of 206 bones, while infant skeletons consist of 270 bones.

4. The DNA in an adult can stretch from the sun to Pluto 17 times.

Our genome contains 23 DNA molecules of which contains five hundred thousand to 2.5 million nucleotide pairs. DNA molecules of this size if coiled are 1.7 to 8.5 cm. If uncoiled, they stretch up to a 5cm average range. There are thirty seventrillion cells in our body, so when they are put together uncoiled, the length will be 37 trillion by 5 cm. It’s said that the length is enough to cover 17 trips to Pluto from the sun.

5. A person can walk around the world five times throughout his or her lifetime.
