Jesus Christ that is such a a severe beating.
I've taken a fair number of L's in my life, some could be considered pretty bad, getting jumped by multiple people and repeatedly kicked in the face, beaten with a large tree branch, one time I was mugged and got wailed on until I stopped trying to get up. I never had anything worse than a fractured wrist. Part of it is knowing how to deal with violence. I'm a terrible fighter, but there's definitely a method to surviving a beating, it's hard to explain. Ralph must have just completely frozen and let someone utterly trounce him.
Most importantly, this is not the sort of beating a mugger gives to someone, even if they were "chased down", they just want to subdue the person and gtfo. This was definitely protracted and motivated by an extreme emotional response.
