Two random blog-worthy observations about hospitals after the first night I've ever spent in one..
At least my local hospital has a simple social engineering security hole that could allow an attacker to be treated without ever being billed. No CVE ID has been assigned, and this hole has not been exploited in the wild. :-P
They're awfully social places for we introverts for whom prolonged (and indeed, unrelenting) polite social interaction tends to be a drain.
Anyway, I'm feeling better aside from a tendency to write "hotel" when I mean "hospital" and "evil-midnight-nose-wiring-demons" when I mean "nurses".
