I have walked out of an ER waiting room with a multiple fractured hand/wrist, after waiting 6 hrs.

I needed to eat, that day.

I bought a brace and splints at a Rite Aid, and just set it myself, while biting down on a wallet, and then taught myself to be left-handed.

Years later, got an xray, Doc was surprised to learn I’d set it myself, said I did a pretty good job.

My having taken a comprehensive combat first aid / trauma response training course at a local gun range, a decade ago, was more useful than the entire US healthcare system.
