Question

Is there a way to quickly remember information just before taking an exam? Walking backwards might be a way to solve this problem. Scientists from the University of Roehampton in the UK said this activity can help people improve their short-term memory.

Researchers asked 114 volunteers to watch a video. After watching the video, volunteers were divided into three groups. One group was told to walk 10 metres forward. The second group walked 10 metres backward. The third group stood in one place. All three groups were then asked 20 questions about what they saw in the video.

The scientists found that the backward- walking group got two more.answers correct on average than the other groups.

This suggests that the relationship between the concepts(概念）of time and space is important considering how our minds form memories. "Time is really expressed via(通過）space,”Aleksandar Aksentijevic, who led the study, told The Daily Mail. When you walk backward, you see things from a different way compared to walking forward. This difference helps people recall things that happened in the past.

And walking backward is not just good for our brains. It is also good for the rest of our body. Compared to walking forward, walking backward is more challenging. This can ameliorate our health, according to New Scientist, Walking backward uses more energy in a short time and burns more calories.

Besides, walking backward is less stressful for our knees. It could.be helpful for people who often have pain in their knees, according to researchers from the Unegon in the US. Walking backward also keeps our spines（脊柱）strong, which can help to reduce pain in the lower back. This might be why many old people like walking backward.
