#2. Younger than he looks: Former WWE Superstar Matt Hardy - 46
Matt Hardy first arrived on the scene in WWE back in 1994, before earning a contract with the company a few years later.
As one half of The Hardy Boyz, Matt Hardy found success in WWE for several years alongside his younger brother Jeff. The former champion's career has been littered with controversy. The love triangle with Edge and Lita even led to his WWE release back in 2005.
Hardy was later able to return but was then released from the company once again in 2010 after seemingly forcing the company's hand. Hardy has since returned to WWE for a third time, but this time was able to allow his contract to expire before making the move over to AEW.
In his personal life, Hardy has welcomed three children with his wife and fellow wrestler Reby Sky. This could have added to the fact that Hardy has aged much quicker than his brother. Whilst Jeff Hardy doesn't look a day over 40 at present, it's hard to believe his brother Matt is just 46.
