Congenital defect, in no way associated with bodybuilding. Amirite?
Yes, as it always is. If bodybuilding related he's still had great resilience, many fall much earlier. Resilient organs, that is. That back injury really messed him up. I remember when he first started showing a tiny imbalance in his lats, before most noticed it. Chad commented on it later. Of course many older lifters have withering bodyparts due to spine issues, like the "dead" calf or calves. Even Dorian has one calf like that.
