The Hardy's will always be one of my favorite tag teams, but at this point, I just think it's time for both of them to call it a career. They both look rather haggard at this point. Jeff, even now in his 40's, still hasn't overcome his personal issues, sadly. Matt looks kinda old and I don't know what else there is for him at this point. If they were to retire now, they can at least walk away with their relative health. It's probably not gonna get any better for either guy healthwise at this stage of their careers/lives.
Sometimes folks think these guys just started in late 1999 or the early 2000's, but they've been wrestling for longer than that, at least since they were jobbers on Raw in the mid 90's. So, there's more wear and tear on those bodies than we even know. They've been doing it for along time. Whatever happens, I certainly wish them the best, though.
