Whats the connection between Genu varum and Rivaldo???

Few days back when reading a orthopedics textbook i came across a condition called GENU VARUM which is usually characterized by outward bowing of legs giving the appearance of a bow. and one of the major causes of it being Vitamin D deficiency.When i goggled it came to know that among many famous sufferers of it world famous Brazilian footballer RIVALDO was one of them.He developed this problem[rather a deformity] during his early childhood days when he couldn't afford even a days meal because of poverty!....Inspite of all these difficulties he managed to become one of all time best footballers of this generation!!!
