It’s like they’re fighting themselves *and* each other.

Everything is harder when you’re drunk. Don’t believe me? Why don’t you try having six or seven beers and then go for a drive? (I’m just kidding, please don’t do this.)

One of the reasons that everything becomes more difficult after a few brews is that alcohol rids you not only of your sense of judgement, but your proprioception — i.e., your body’s ability to know where it is and what it’s doing.

This can make fighting a bit of a disaster, as can be seen here.
