墨西哥六岁神医开坛授课（在线收听）

At 6 years old, this little first grader from a small town outside the Mexico City is knocking the medical students off their feet with his knowledge of osteoporosis. M lectures students more than three times his age about the bone disease. Professors at the Autonomous University of the state of Mexico say he is open to learning something new everyday. M says he is not gifted or a genius. He says he is just a normal boy and student although he admits that he is good at memorizing information and loves to learn. By the age of three, he knew the capitals of 90 different countries.
