It's difficult to believe the man was in no pain and did not seek medical care until he was involved in an automobile accident. I've hit my head a few times on cabinets and it would have sort of lobotomized this guy.
Regarding the pain, though, don't they say that your brain has no pain receptors? Granted, there's gotta be a difference between being awake for brain surgery and walking around like that, but...
True, but I imagine showering or bathing one's hair in that condition would be precarious proposition, one could use a bathing cap while doing rest of body but that would still leave the undamaged head parts needing a wash.
