What were you doing at 17 years old?

This guy sailed around the globe alone. He's the youngest to ever do it:

Mike Perham suffered knockdowns and damage to his yacht during the 24,000-mile (38,700-km) trip and the teenager from Hertfordshire, southern England, said he was now looking forward to a "good meal and a very good night's sleep."

Fewer than 250 people have sailed solo around the globe, but his record is already in jeopardy if a 13-year-old Dutch girl persuades a court to allow her to set sail.

Perham, who started sailing aged seven, was the youngest person to sail across the Atlantic Ocean, aged 14, in 2007.
