5、It has long been known that the human body can be a powerful weapon. Now a study of Welsh emergency room patients has concluded that kicks are much more likely to cause serious injuries than attacks using other parts of the body -- or even attacks using objects such as knives or bats.

Researchers at Cardiff University in Wales examined the medical records of nearly 25,000 people treated in a local hospital between 1999 and 2005. They found that while-kicks were less common, such attacks caused greater damage than either blows or attacks with weapons.

Kicks were more likely to cause serious head and brain injuries. Besides, kicks were more likely to cause broken bones.

Of the more than 31,000 recorded injuries examined for the study, Shepherd's team found that about 7 percent were due to being kicked. About 21 percent of the injuries were caused by blunt （鈍的） or sharp weapons, while slightly more than 50 percent were due to blows.

The researcher notes that overall, severe injuries from violence seem to drop in the United Kingdom, although exact measurement remains a problem.

"We have evidence that shows police records are not a reliable measure of violence, and that reliable measures of violence are crime surveys and injury statistics."

Similarly, the level of violence in the United States has been on a downward trend since the 1980s, said Fred Rivara, founding director of the Research Center in Seattle, Washington.

But rates of lower-level violence in the U.S. have not been thoroughly studied, he said.

"There have been a number of studies looking at the risk of guns versus blunt or sharp objects in the United States," Rivara said, "but we haven't seen anybody looking at feet or fists versus weapons."
