What I don't understand about this theory, is, that you would then expect athletes of all sizes to die sooner... Certainly the heart of an athlete has gone a lifetime working harder than a non athlete... Maybe I'm misunderstanding something about the height/age correlation...

My guess, is your misunderstanding lies in biology in general. There is no constant maximum heart effort per lifetime. The heart is a muscle, if muscles are not used they become weak, conversely when muscles are used they become stronger and can grow (see: weight lifting). Also there is more to staying alive than a heart that beats.
