Here's his promo from just last night on RAW (complete with line about how "every man's heart will beat it's final beat.")
2014 WWE Hall of Famer Ultimate Warrior speaks: Raw, April 7, 2014 - YouTube
With hindsight, I guess, maybe he doesn't look so great here? (Edit: At about 3:00, he's completely out of breath - of course, it was a Warrior promo, so that can happen). He was a 54-year old guy, but if you look at his wikipedia photo and other recent photos - he doesn't look so great here by comparison. Could just be me seeing things that aren't there.
