#6. Former WWE Champion Jeff Hardy - 44 years old
Jeff Hardy is a former World Champion who's recently in the news because his WWE contract is set to expire next year.
Hardy and his brother Matt made their return to the company back at WrestleMania 33, but whilst Matt has moved on to a stint in AEW, Jeff has remained in WWE because of recent layoffs due to injury.
Hardy debuted in WWE when he was just 15 years old and has since wrestled for numerous other companies over the past three decades.
#5. Former WWE Champion AJ Styles - 44 years old
AJ Styles made his WWE debut as part of the Royal Rumble back in 2016 and has since been able to capture the top championship. Styles made a name for himself in IMPACT Wrestling ahead of his WWE debut and has been a consistent force on RAW over the past few months.
The Phenomenal One is aware that he is nearing the end of his career and has been happy to help new talent who are making their way through the ranks. This includes his recent RAW Tag Team Championship reign with Omos.
