     "High income is not as good as high age, and high age is not as good as high spirits."

     Generally speaking, the rich are happier because money can buy them goods and services and it is the

consumption (消费) of these materials that increases one's enjoyment of life. Especially nowadays, money

seems to be one thing that drives the people around. "Human beings live for money while birds die for food."

-a well-known Chinese saying is quite quotable (适宜引用的) to explain the present society. Some people try

every means to make money at the cost of others' interests. These people harm others to benefit themselves.

They think the more money they make, the happier they will be.

     In addition to money, people's happiness was affected by other factors. High age is what many Chinese

are dreaming of. Longevity is the very term that people often use to pray for their dears and elders. So there

are many books and theories that introduce the way of living longer. Dancing, jogging, dieting, even singing

and shouting together are said to do good to one's health.

     However, some people think that high spirits is the most important to the quality of one's life. If you are

in high spirits, you'll find everything pleasing and comfortable in life: warm sunshine, blue sky, white clouds,

happy birds, comfortable breeze (gentle wind), sweet smiles, and so on. You seem to have friends across the

world. Your life will be happy at every moment. You will be in good health and can make more money if you

live longer.

     In one word, let's keep ourselves in high spirits, therefore we could keep longevity and make considerable

money at the same time.
