Sergio discusses four topics in his blog: Van Halen, a rock band known for their lead guitarist Eddie Van Halen's speed and an upcoming tour; Rayados, a successful Mexican soccer team that has won championships and is currently in second place; Def Leppard, a hard rock band whose drummer Rick Allen continues to play despite losing an arm; and the Dallas Cowboys, an American football team that has won the most Super Bowls but is having a poor season and Sergio hopes they will make changes to win more championships.
