Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems, and possibly cancer.

1    Some people express anger openly in a calm reasonable way. Others burst with anger and scream and yell. But other people keep their anger inside. They can not or will not express it. This is called repressing anger.

For years many doctors thought that repressing anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain releases the same hormones (荷  尔  蒙  ） ， They speed the heart rate, raise blood pressure, or sugar into the blood，etc.   2

How can a creature weighing over 5 tons and normally taking 150 kilograms of food and 120 liters of water per day survive in a desert environment?

In the southwest African country of Namibia,and the Sahara lands of Mall further north,the desert elephant does just that.

Although not regarded as a separate species from the African elephant,the desert cousin differs in many ways.Their bodies are smaller,to absorb less heat,and their feet are larger for easier walking across sandy surfaces.They are taller,to reach higher branches.They have shorter tusks(象牙),and most importantly,longer trunks to dig for water in riverbeds.

Desert elephants can travel over 70 kilometers in search for feeding grounds and water-holes,and have a larger group of families.They drink only every 3-4 days,and can store water in a “bag” at the back of their throat,which is only used when badly needed.Desert elephants are careful feeders—they seldom root up trees and break fewer branches,and thus maintain what little food sources are available.Young elephants may even eat the dung(粪便) of the female leader of a group when facing food shortage.

During drought they are unlikely to give birth to their young but with good rains the birthrate will increase greatly.Desert elephants have sand baths,sometimes adding their own urine(尿液) to make them muddy!

As we continue to overheat our weak planet,it can only be hoped that other animal species will adapt as extraordinarily well to change as the desert elephant.
