Must have had something wrong with him to begin with, no? Or was it directly in the temple? I was hit across the head with a bottle of whiskey just this christmas day night and although I did end up going to hospital 2 days later I was fine. I can't imagine one punch killing someone...
Nope, perfectly healthy, just sometimes humans are squishy, I knew someone who got in a fight, a few days later died because of internal damage, just did not know.
He was dead by the time he hit the floor, I was working for the police for a little, and we had to watch the CCTV, they were drunk, and the guy must of hit him with so much force. It does happen though.
I think the pain we feel when we're intoxicated always gets multiplied by at least 5x when we're sober the next day.
if you could do it, get medical inspection. You don't want this hustle to bother you when you're older. Sometimes internal damage causes you a lot more problem in the future than now. Better to not get yourself into financial problem should it be worse in the future and you have to get special treatment.
