If you are afraid of the dark,it’s not a big deal.It’s perfectly normal to feel afraid After all,animals do too. “Fear matters,”says Karen Warkentin,an ecologist.“It’s a good thing,” she adds, “because fear makes you do things that keep you alive.”
Like kids,many animals experience fear and they respond to the feeling in variety of ways.A
frightened turtle pulls its head and legs inside its shell.A small fish will swim away when a big,hungry fish approaches.
Some animals respond to fear in ways you might not expect.The first example is that the fear of being eaten can scare some frogs right out of their eggs. Warkentin made the surprising discovery while studying red—eyed tree frogs in Costa Rica.
In this species,female frogs attach jellylike clumps(果冻一样的块状物)of their eggs to the undersides of leaves.The leaves hang on branches that dangle(悬挂)over ponds.After they hatch from the eggs,the tadpoles(蝌蚪)then fall into the water,where they eventually grow into
adult frogs.
Tree frog eggs usually grow for 6 days before hatching.If they sense that a hungry snake is about to attack,however,they can hatch up to 2 days ahead of schedule. As the snakes are unable to swim,by falling into the water early,the tadpoles can escape.
If hatching early helps protect red—eyed tree frogs from snakes,you might wonder why their eggs don’t always hatch sooner.It turns out that hatching early brings its own danger.Once tadpoles land in the water,hungry fish and other animals like to eat them too.Staying in their eggs for a full 6 days,then,allows frog embryos(胚胎)to grow big and strong.This extra growth improves their chances of surviving in the water.

Have you ever heard the story of the four-minute miles? Many years ago, people believed that it was impossible for a human Being to run a mile in less than four minutes until Roger Banister proved it wrong in 1954.
What happens if you put an animal in a pond? Any animal, big or small, will swim its way through. What happens when someone, who doesn't know how to swim, falls in deep waters? They drown. If an animal who has not learnt swimming could escape by swimming, why not you? Because you believe you will drown while the animal doesn't.
Have you ever wondered why the letters are organized in a particular order on your keyboard? You might have thought it is to increase the typing speed. Most people never question it. But the fact is that this system was developed to reduce the typing speed at a time when typewriter parts would jam(堵塞) if the operator typed too fast.
These three cases show the power of our beliefs. There is no other more powerful directing force in human behavior than belief. Your beliefs have the power to create and to destroy. A belief delivers command to your nervous system.
I used a snake in my workshops for children to show them how unrealistic some of their beliefs are. Students of a school in India, said snakes are slippery and slimy and poisonous. After doing an exercise for changing beliefs, they handled my snake and found it to be dry and clean. They also remembered that only     three types of poisonous snakes exist in India.
Did this story end the way you thought? Review your beliefs now and find out which ones you need to change?
