A: their left from their right
MORE THAN 20% OF PEOPLE CAN’T TELL LEFT FROM RIGHT: You may think that telling the left from the right is a basic skill, but it can be challenging for some. According to Dr. Gerrard Gromley of Queens University Belfast, nearly 20 percent of college professors and approximately 26 percent of college students can’t tell their left from their right. Gromley argues that confusing the two sides is a simple mistake that many make but can be deadly in certain situations – particularly for those working in the medical profession. He’s calling for testing to rule out those who struggle with distinguishing between the two directions. (Daily Mail)
