A while back I had to have a long and unpleasant dental procedure - a bone graft so I could get an implant in an area where the bone had been damaged - this took about 4 hours. During this time the dentist played music - mostly various works selected at random by Hans Zimmer.
At one point things got a bit intense as apparently I have very hard bones - which meant that quite a bit of force was being used. The music playing during this part of the procedure was "No Time for Caution" - which I thought was hilarious... and this fact kind of took my mind off of things.
Hah, that's great.
My dentist has overhead TVs in all of the rooms. Before a longer appointment I asked if I could bring some over-ear headphones to connect to the TV. Surprisingly nobody had asked that before but they were fine with it. The headphones drowned out the drilling and other noises and helped me zone out into some shows.
I'm very short sighted so TVs wouldn't work for me, but I also tend to keep my eyes tight shut in case I see any of the ghastly instruments being used!
[During the bone graft I did open my eyes briefly and saw a small for clearly identifiable circular saw].
Once you get down to bone, especially larger ones, parts of the surgery turns into masonry and carpentry. Including the tools. Power drills are valid tools in joint replacements or fracture stabilization.
Hans Zimmer is my soundtrack of choice for focus (Dune 2 is specially good). Found out that a colleague also had the same taste which was surprising for me, now I imagine it is a common use case for his music.
