Not for 7 years, though. Unless he started wrestling indy's and ECW at the age of 15. He was already a popular star by age 21 in the WWE with his brother. I'd say Hardy is one of the very few to start wrestling for the world's biggest wrestling organization at a very young age.
At 37, he's still a high risk high flier. Took a wicked nasty bump on the ring steps a few months back. Hope he doesn't end up like the Dynamite Kid when he gets older. Hardy is all about entertaining the fans.
