His jacket was also stained with blood. Explaining the injury, Armstrong shared that he then “swung by the Aspen Valley Hospital” in order to get himself checked out. “For the 46 yrs prior to today I completely would have blown off getting checked. Not now,” Armstrong added, before sharing a funny story about how, as fate would have it, he already sort of knew the doctor who took care of him at the emergency room.
