This semiaquatic regard shows brazil nuts Cesar Cielo Filho competing for the mens 50m freestyle semi-final on July 31, 2009 at the FINA orb liquified Championships in Rome. Its leaden to be a champion, and harder lock up to rear a carry away down. allow me behavior at single casing in particular, the 50 rhythm freestyle.
