The reason for said confusion was due to how great of shape DiBiase was in. In fact, in wrestling circles, DiBiase was well known for keeping himself in peak physical condition, to the point that he once wrestled a Texas Death Match against Terry Funk that lasted four hours and ten minutes. That is not a typo; DiBiase and Funk legit wrestled four hours and ten minutes, and not just in any type of match, but an old school Texas Death match. While not as violent as some of the Texas Death matches seen in AEW today, the match up was still grueling, and under old school Texas Death rules, forced the wrestler to win a match by not only getting a pinfall, but keeping their opponent down for a ten count afterward. Because of this, DiBiase was predisposed to both heart disease and potential heart attacks, though it's unclear whether he was aware of this at the time of his death.
