Some people (me, for example) couldn’t water ski if their life depended on it, but it seems like some people were just born into it. Well, that’s certainly true in the case of Zyla St. Onge, who may hold the world record for the world’s youngest water skier.

That’s right, at only six months of age, Zyla can’t yet walk, but she can water ski like no one’s business. Of course, it helps when your parents are both professional water skiers who knew just how to prepare a toddler to ride the waves like her parents.
