Paleoanthropologist Juan Luis Arsuaga (Madrid, 68 years old) says that our brain feeds on glucose and stories. And he is a counting machine. To begin with, he explains that he is in this world thanks to Real Madrid. His father, Pedro María Arsuaga, played as a left winger for the white team in the late 1940s. He was injured and was sent to the stands to watch the games. There he noticed a young woman who always sat next to him. The footballer knew that his career would be short, so he enrolled in economics at the Complutense University. One day, going down to class on the tram, he met that girl again, who was studying philosophy and literature. They talked, they liked each other and from there Juan Luis came out.
