HERE for your delectation is yet another example of why the definition of miracle really needs to read "highly unlikely happenstance." The article starts with "A miraculous thing" but then goes on to state, oh so very clearly, that there was nothing at all miraculous about this guy's recovery. Simply a case of letting a muscle rest.
I don't think many personal trainers would declare it a miracle if an over-taxed muscle recovered once the stress was removed. Do you?
