#1. Roman Reigns - Could retire from WWE earlier than expected
There has been a big change in the lifestyle of WWE Superstars this generation. During the Attitude Era and eras before, wrestlers didn't live the healthy lifestyle that they do today.
While it didn't apply to every wrestler of the past, a large portion of them were victims of the hectic schedules that forced them to resort to alcohol, pills, and in many cases, harder drugs.
The career span of both male and female WWE stars may increase this generation, with virtually every superstar being in top physical condition as well as having a sense of financial responsibility.
It's shocking to imagine Roman Reigns retiring by 2024, but if he does, it would mark the end of a 12-year career in WWE. Reigns has hinted at having Hollywood aspirations, and the possibility of retiring in three years or less.
However, he has the least chance of retiring by 2024 on this list. In an interview ahead of WrestleMania 37, The Tribal Chief said that he was working on further improving his physical condition so he can maximize to his full potential.
Given how motivated Roman Reigns seems to be in his current WWE run, he may just want to expand his wrestling career for a few years longer.
