Can you rewire a brain monitor or a heart monitor or one of those things that goes on your finger to have an audio output instead of a visual one?

Yes you can but you need knowledge of electronics (personally I do not wish to go into detail because I do not know what you have/ know) Answer its actually fairly simple, take the cord out of the monitor, then hook it up to a jack of any size. For example, a 1/4 inch for guitar amps. This will probably give a monotone, and may not be in the human hearing range.

Most heart monitors are both visual and audio Answer In many cases, you just need a dongle to split the line coming from the heart monitor. It's small and kind of flat, like a slim SD media card reader and will have two plugs on it. Not sure on the brain montor, but most heart monitors after '88 do audio.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
