Boston man, John Ferraro, nailed a new world record in Italy.

Ferraro pounded 38 nails into a board with just his forehead in under two minutes. He also holds the one minute record at thirteen nails and has the world record for most concrete blocks broken on the head with a bowling ball in three minutes.

The reason this man has such a strong head is due to the fact that his head is actually more than twice as thick as the average human skull. John's skull is 16 millimeters thick whereas the average human skull is only about 6.5 millimeters thick.

And if breaking three world records wasn't enough, Ferraro also works as a professional wrestler under the name "Gino Martino."

Looks like the biggest and best heads come from Italy!
