Jake Paul is only 24, but he's suffering from memory loss and slurred speech, and it's largely because of boxing -- and it could get even worse with tonight's fight.
Jake appeared on "In Depth With Graham Besinger," and talked about something boxers rarely discuss when they're still in the game -- how boxing messes up their head.
Jake told Graham, "I notice it in conversations with like, with my girlfriend or friends, like, not remembering something that I should be able to remember that happened a couple days ago."
