I never considered music as a squick, but then again I didn't play all that much in school, and only then in band. I haven't picked up a clarinet in years, but I could probably still play "Pomp and Circumstance" by heart based on how many times I had to play it.

But medical issues, yes. I've worked in healthcare/healthcare IT since I was 16 years old, and I often scream at the TV/monitor when I'm watching a scene and they do something stupid like put the IV drip chamber at the vein just off the needle. It's like really? Are you THAT stupid? Have you never seen another movie or TV show that showed a drip chamber hanging off the IV bag?!?!?!
