If Mickey Mouse slips (滑倒)on a banana skin on TV, viewers laugh. But for ordinary people, falling is not
36 . For e
xample, if you
37 over a stone or fall off your bike, you have to take days to get well. For
38 people, the result of a fall could be worse.
Scientists at the University of Pittsburgh, USA, wanted to know why some people are
39 likely to fall than others.
The researchers found that
40 means more than planting your feet on the ground and standing tall. Your brain
41 your sense of balance with information from your eyes and inner ears and the
42 from your feet and legs. If something goes wrong with any of these, you’re
43 to fall. People
44 to fall more often as they grow older because their senses are slower.
State of mind is important too. The research shows that when people know they’re walking on a slippery surface, they
45 their pace and walk with flatter feet. As a result, they fall less often.
“We actually
46 people slip and fall,” researcher Mark Redfern said. People of different ages fall on
47 in his lab. Cameras 48 their falls and a computer analyzes the information. Scientists then can
49 people who fall often how to be more watchful.
“If they get
50 to a lifelike but controlled environment, people can
51 learn to handle the
52 thing,” Redfern said.
Falls happen to everyone sometimes.
