How schools kill creativity
The present creativity retarding worldwide education system needs to be changed and reformed according to what Sir Ken Robinson has presented in his talk ‘How schools kill creativity‘ at the TED conference in February 2006. Sir Ken Robinson is an English author, speaker, and international adviser on non-profits, education, and arts bodies. He was born in March 4, 1950, Liverpool, United Kingdom.
The education system, which has been developed in 19th century, is focused on making students capable of getting jobs. It is as like as industrial production system which produce hundreds of graduates and push them into job fields .
As a result, talented people do not get the sense of achievement. Even they are not valued at school for the things they are good at. Eventually, their high creative possibilities get wasted.

How do vampire bats survive
Much like its fictional counterpart of books and movies, the vampire bat sleeps during the day - usually in dark caves - ventures out at night to feed. the vampire bats can be found in the tropical forests of South American through to Mexico.
most of the vampire bat’s victims are large herbivores such as horses and cows, though human attacks are not unheard of. Most of the time, victims will rarely notice as the bats only consume about a tablespoon of blood per sitting; this said, they are often accused of spreading rabies.
Contrary to popular think, they don't actually ‘suck’ the blood either, but rather nip the skin with their sharp teeth and then lap at the blood that flows out.
Like all bats they use echolocation to get around, but they have also evolved some unique ways to hunt. For one thing they have special thermoreceptors on their noses, which - via infrared radiation — enable them to pinpoint where blood flows closest to the prey's skin, while an anticoagulant in their saliva stops blood clotting before they've had their fill. Vampires are also unusual within the bat family for their ability to walk, climb and even hop along the ground — ideal for stealthily approaching slumbering victims.
