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. 53 you see someone fall, think about why and offer a helping 54 . This person’s painful experience may 55 you from falling at the same place.
