4. "There was a large crowd outside, including my teachers and other parents, people looked quite agitated," Sun said of the moment he was rescued.
5. A fascinating study from researchers at the University of North Florida reveals that running barefoot may actually improve your memory more than running with shoes. While most memory studies seem to take place in a laboratory or room where everyone sits at a table, this experiment definitely introduced an interesting idea to the search for a better memory. The experiment focused on something called "working memory," which is the human ability to process information and recall details throughout life. The scientists published the results of their study in "Perceptual and Motor Skills," and found that running barefoot resulted in a not-insignificant memory boost when compared with memory performance after running with shoes. The researchers found that tossing your shoes off and running for about 16 minutes at a comfortable pace could result in a 16% improvement in working memory performance.
