     For thousands of years,people have been debating the meaning of happiness and how to find it. From

the ancient Greeks and Romans to current day writers and professors,the debate about happiness

continues. hat makes some happy? In what parts of the world are people the happiest? Why even study

happiness? The Greek philosopher Aristotle said that a person's highest happiness comes from the use of

his or her intelligence. Religious books such as the Koran and Bible discuss faith as a form of happiness.

The British scientist Charles Darwin believed that all species were formed in a way so as to enjoy

happiness. People throughout history may have had different ideas about happiness. But today,many

people are still searching for its meaning.

     How do you study something like happiness? You could start with the World Database of Happiness at Erasmus University in Rotterdam,the Netherlands. This set of information includes how to define and

measure happiness. Some findings are not surprising. For example,the database suggests that married

people are happier than single people. Peoplewho like to be with other people are happier than unsocial

people. But other findings are less expected: People with children are equally happy as couples without

children. And wealthier people are only a little happier than poorer people.

     Positive psychology is the new term for a method of scientific study that tries to examine the things that make life worth living instead of life's problems. Traditional psychology generally studies negative situations like mental suffering and sickness. But positive psychology aims to study the strengths that allow people

and communities to do well. Thereis also an increasing amount of medical research on the physical qualities of happiness. Doctors can now look at happiness at work in a person's brain using a method called

magnetic resonance imaging (核磁共振成像),or MRI. For example,an MRI can show how one area of a person's brain activates when he or she is shown happy pictures. A different area of the brain becomes

active when the person sees pictures of terrible subjects.
