Newscaster Dan Rather suffers from poor proprioception, meaning that he has poor spacial awareness of where parts of his body are in relation to other parts. The upshot is that he tends to walk into a lot of door frames when trying to go through doors. As might be expected, this hurts, so he takes a good deal of aspirin. The combination of the blood thinning properites of aspirin and walking into doors has caused him to develop very large bruises on his arms. The bruises were so bad that at one point his co-workers suspected him of getting beaten by his wife.
