Half of this large Brazilian family carries a special trick up their sleeves—if you high-five them, they high-six you in return.
Fourteen of the 23 members of the da Silva family were born with six digits on each hand. They don’t consider the anomaly detrimental though. Quite the opposite, they hope for their children to inherit it.
“When we get pregnant and go for a scan, we just want to know if it’s five or six digits. We don’t care if it’s a boy or girl,” one of the family members told BBC in 2015.
As opposed to some other anatomic anomalies, their extra fingers are not just limp outgrowths, but real, functioning digits. They can take advantage of them playing piano, guitar, or—as expected in the country of soccer—get a better grip on the ball as goalkeepers.
The condition is called polydactyly and is fairly common among newborns. A 1994 study on data from Jefferson County, Alabama, found it in about one in 430 white males, one in 1660 white females, one in 74 black males, and one in 90 black females.
It is rare, however, for the extra fingers to be fully functional.
Joao Assis da Silva, 18, aspires to be a goalkeeper, taking advantage of his peculiarity.
“I think it’s good because my hand is bigger than other hands and I have a better grip. I can hold the ball much better than people with five fingers,” he told BBC.
He has a difficulty, however, getting goalkeeper gloves that fit. “I have to buy two [pairs of] gloves, cut one finger from a glove [and] put it on [the] other so I can have a six finger glove,” he said.
Another family member, Maria Morena, said her piano teacher wished to have extra fingers too, since it can enable the player to reach more keys. Indeed, 12 digits would allow you to play chords otherwise anatomically impossible.
But having extra fingers isn’t all beer and skittles. For example, manicure takes 20 percent longer.
