In the next one second, 4,000 stars will be formed, 16,000,000 litres of water will evaporate from the oceans and 3 sharks will be killed. All the while, your body will make 17 million red Blood cells.

Unlike other types of cells, red blood cells don’t contain a nucleus, mitochondria or ribosomes. That’s a good thing, because it leaves room for millions of haemoglobin molecules that transport oxygen to your organs. As well as red blood cells, your blood is made up of plasma, platelets and white blood cells. It also contains trace amounts of gold - about 0.2 milligrams, to be exact. Together, these elements make up the blood that keeps you alive - unlike those 3 sharks... RIP.
