1.
Nowadays. millions of people misuse and even overuse pain medications and other drugs. Research by the American National Institute on Drug Abuse (NIDA, 1999) shows that around 2% of the population over age 12 were using drugs non-medically.
2.
NIDA views medications as a powerful force for good in the contemporary world. They reduce and remove pain for millions of people suffering from illness and disease. They make it possible for doctors to perform complicated surgery to save lives. Many people afflicted by serious medical conditions are able to control their symptoms and become active, contributing citizens. NIDA points out that most individuals who take these drags use them in a responsible.

Nevertheless, overuse of drugs such as opioids（类鸦片）, central nervous system (CNS) depressants and stimulants does lead to harmful reliance in some people and is therefore becoming a serious public health concern. Although this abuse affects many people worldwide, particular trends of concern to the medical profession in the US appear among older adults, teenagers arid women.
4.
Though it may be a surprise to many, the misuse of medications may be the most common form of drug abuse among the elderly. Dr Kenneth Schrader of Duke University, North Carolina states that although the elderly represent about 13% of the US population, those aged 65 and over account for the consumption of one third of all drugs. People in this age group use medications roughly three times more than the general population and have poorer compliance with instruction for use. In another study of elderly patients admitted to treatment programs, 70% were women who had overused medicines.
5.
Unfortunately, this trend among women does not only affect those aged over In general, among women and men who are using either an anti-anxiety drug or a sedative, women are twice as likely to become addicted. In addition, statistics compiled for 12-17 year olds show that teenage girls are more likely than teenage boys to begin overusing psycho therapeutic medication such as painkillers, tranquillizers, stimulants and sedatives.
Dr. Wiseman started the “laugh lab” project in September 2001. It is the largest study of humor. Participants are invited to log on the laugh lab website, give a few personal details, tell their favorite jokes and judge the jokes told by other people.
Their project will last for a year, and the organizers hope to finally discover the world’s funniest joke. But there is also a serious purpose. The researchers want to know what people from different nations and cultures find funny. And they want to find out the differences between male’s and female’s sense of humor. The idea is that if we want to understand each other, we have to find out what makes us laugh.
This is a subject that has long interested psychologists (心理学家) and philosophers (哲学家). Most of the time, people are not completely honest. We do things that society expects us to and say things that help us get what we want. But laughing cannot be controlled. When we laugh, we tell the truth about ourselves.
By December 2001 over 10,000 jokes had been submitted (公认的). This gave the scientists enough evidence to make early conclusions. It seems that men and women do have different senses of humor, for example.
“Our findings show the major differences in the ways in which males and females use humor,” said Dr Wiseman. “Males use humor to appear superior (高傲的，有优越感的) to others, while women are more skilled in languages and prefer word play.”
Researchers also found that there really is such a thing as a national sense of humor. The British enjoy what is usually called “toilet humor”. But the French like their jokes short and sharp, “You’re a high priced lawyer. Will you answer two questions for $ 500?” “Yes. What’s the second question?”
The Germans are famous for not having a sense of humor. But the survey found that German participants were more likely to find submitted jokes funny than any other nationality. Perhaps that proves the point. Is this joke funny? I don’t know, but let’s say yes, just to be safe.
Dr Wiseman and his workmates also submitted jokes created by computer. But none of those who took part in the survey found any of them amusing. Perhaps this is relief (安慰). Computers already seem like they can do everything. But at least they should leave the funny things to us.
