Can 6-fingered family help Brazil win World Cup?

Fourteen members of a Brazilian family, the Da Silvas, were born with six fingers on each hand and six toes on each foot thanks to a rare genetic condition called polydactyly. The family, who live near the capital, Brasilia, are staunchly proud of their additional digits, and say they believe they can help the national team win their sixth title in Rio de Janeiro next month.
