     It is easier to go downhill than to climb uphill. So it is easier to fall into bad habits than into good ones.

     Bad habits do not come suddenly. They come little by little without one being aware of their danger.

 School boys first pick up little bad habits in school and on the street. When they can't write their lessons,

  they copy from their schoolmates. If they see bigger boys smoking, they also want to learn to smoke. If

 they see their friends gambling they want to gamble. When they get bigger, the habits become stronger and

  stronger so that they can no longer get rid of them. From copying they learn to steal, from gambling, they

 learn to cheat. At last they become suspected by everybody. How necessary it is that we get rid of the

 bad habits in the beginning!

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,生气).

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.
