Walking backwards might be a solution. 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, participants were split (分成) into three groups. One group was told to walk 10 meters forward. The second group walked 10 meters 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(平均) than the other two groups.This suggests that the link between the concepts (概念) of time and space is important in terms of how our minds form memories. “Time is really expressed via (通过) space,” Aleksandar Aksentijevic, who led the study, told the Daily Mail. When you walk backward, you see things from a different angle (角度) 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 help us improve our fitness, according to New Scientist Walking backward uses more energy in a short time and bums more calories.In addition, 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 University of Oregon in the US. Walking backward also keeps our spines (脊柱) strong, which can help to ease pain in the lower back. This might be why many old people like walking backward.26 .
