"The face, head and chest are more sensitive to changes in temperature than the rest of the body, making it feel as if covering them up does more to prevent heat loss. In fact, covering one part of the body has as much effect as covering any other."

"Another myth exposed by the study was that sugar makes children hyperactive. At least a dozen high-quality studies have investigated the possibility of a link between children's behaviour and sugar intake, but none has found any difference between children who consumed a lot and those who did not."
