Humans Instinctively Know How And When To Smile
In 2004, Dr. David Matsumoto attended both the Olympic Games and the Paralympic Games. By comparing the facial expressions of blind and sighted athletes, he concluded that certain facial expressions appear to be innate in humans, rather than visually learned. Athletes who were born blind displayed the same kinds of expressions as sighted ones, including joyful smiles when they won and disappointed frowns when they lost.
