“PFO”…”Not another TLA”, I hear you groan…
PFO is a three letter acronym that stands for “pissed, fell over“… A disturbingly frequent presenting complaint to emergency departments around the world.
Here’s a bar chart showing the pattern of injuries that result from PFOs, according to blood alcohol concentration:
From: Johnston JJ, McGovern SJ. Alcohol related falls: an interesting pattern of injuries. Emerg Med J. 2004 Mar;21(2):185-8.
The bottom line according to @precordialthump:
At a BAC of about 2.5 g/L most people are too drunk to put their arms out to break their fall…
So they fall flat on their faces…

Alternate theory at 2.5g/L: people become so annoying to others around them, so that their only course of action in order to shut them up, is to hit them in the head. Then they fall flat on their face……..
