The Pacific island nation of Nauru used to be a beautiful place．Now it is an ecological disaster area．Nauru's heartbreaking story could have one good consequence-other countries might learn from its mistakes．

For thousands of years，Polynesian people lived in the remote island of Nauru，far from western civilization．The first European to arrive was John Fearn in 1798．He was the British captain of the Hunter, a whaling ship．He called the island Pleasant Island．

However, because it was very remote, Nauru had little communication with Europeans at first．The whaling ships and other traders began to visit，bringing guns and alcohol．These elements destroyed the social balance of the twelve family groups on the island．A ten-year civil war started，which reduced the population from 1,400 to 900.

Nauru's real troubles began in 1899 when a British mining company discovered phosphate(磷酸盐)on the island．In fact，it found that the island of Nauru was nearly all phosphate，which was a very important fertilizer for farming．The company began mining the phosphate．

A phosphate mine is not a hole in the ground；it is a strip mine．When a company strip-mines，it removes the to player of soil．Then it takes away the material it wants．Strip mining totally destroys the land．Gradually, the lovely island or Nauru started to look like the moon．

In 1968，Nauru became one of the richest countries in the world．Every year the government received millions and millions of dollars for its phosphate．

Unfortunately, the leaders invested the money unwisely and lost millions of dollars．In addition，they used millions more dollars for personal expenses．Soon people realized that they had a terrible problem—their phosphate was running out．Ninety percent of their island was destroyed and they had nothing．By 2000，Nauru was financially ruined．Experts say that it would take approximately$433，600，000 and more than 20 years to repair the island．This will probably never happen．

Like distance runners on a measured course，all of us will move through time in a roughly predictable pattern．

In the first stage of our lives，we develop and grow, reaching toward the top of physical vitality(活力)．

After we grow up，however, the body begins a process of gradually wearing out．

A new awareness of physical fitness may help lengthen our years of health and vitality，yet nothing we do will work to stop the unavoidable force of aging．

Most of the changes of aging take place deep inside the body．The lungs become less able to take in oxygen．Powerful muscles gradually lose their strength．The heart loses power and pumps less blood．Bones grow easier to break．

Finally, we meet a stress，a stress that is greater than our physical resistance．Often，it is only a minor accident or chance infection(a disease caused by virus)，but this time，it brings life to an end．

In 1932，a classic experiment nearly doubled the lifetime of rats，simply by cutting back the calories in their diet The reason for the effect was then unknown．

Today, at the University of California at Berkley, Dr．Paul Seagle has also greatly lengthened the normal lifetime of rats．The result was achieved through a special protein limited diet，which had a great effect on the chemistry of the brain．Seagle showed that within the brain，specific chemicals control many of the signals that influence aging．By changing that chemical balance，the clock of aging can be reset．

For the first time, the mystery of why we age is being seriously challenged．Scientists in many fields are now making striking and far-reaching discoveries．

An average lifetime lasts 75 years，yet in each of us lies a potential for a longer life．If we could keep the vitality and resistance to disease that we have at age twenty, we would live for 800 years．

Heading off to college this year? Here are some fashion tips from our experts you should keep in mind：

Dress to impress．Stylist and business consultant Daniela Smith says，“Girls should keep in mind that your college professors will often be the bridge that connects you to your future career and your classmates will become your professional network，You don't need to dress like you're going to the office, but you．should display all ability to properly present yourself with appropriate maturity and confidence，and look put together．”

Logo mania(品牌狂热症)．Wearing the loges of brands aimed at younger customers physically identifies you as part of that age group，so consider the targeted age group of the stores you shop at．It's tempting to load up on loges，especially well-known loges that signify high-end brands．But consider this：college is a time of self-discovery, a chance to develop your own personal style．Instead of wearing loges head to toe，“walking advertisement”-style，why not express who you really are?

Wear real pants! The combination of leggings and baggy shirts is all too common on college campuses．Smith points out that leggings，yoga pants，and Sweatpants ale entirely unacceptable in public unless you're exercising．Although leggings worn as pants are a common trend among high school and college girls，they are not an appropriate choice for daywear；As a young woman, your style choice should begin to reflect your maturity level．So，get rid of leggings and wear real pants!

Keep the cute factor to a minimum．Stay away from sweaters and T-shirts with smiling animals, cartoon characters，or Hello Kitty on them．Sure，kittens might be cute，but they're not doing you any favors in the style department．Dressing too cutesy can take years off your look，and not necessarily in a good way!
