#4 Rey Mysterio - 45 years old
Rey Mysterio has seemingly been around the wrestling world for as long as many fans can remember. From his standout match at Halloween Havoc in 1995 to the current feud with Seth Rollins on SmackDown, Mysterio has been a headliner in the business for more than three decades after the star made his debut at the age of 14.
Mysterio has had numerous stints with WWE but his most recent one has allowed him to also bring his son and daughter into the business. It's still hard to believe Mysterio is just 45 years old with a 22-year-old son.

#3 Edge - 46 years old
The Rated-R Superstar, Edge, was forced to retire from the business almost a decade ago due to a neck injury but the former World Champion has been able to return to WWE and have a career resurgence.
Edge was forced to sit on the sidelines for almost nine years, which could be why the 11-time World Champion is still wrestling at the ripe old age of 46. Given the displays he has put on over the past few months, Edge has shown that he hasn't missed a beat in the ring.
