At the beginning of this pandemic, I watched a 2-3 min video of a Turin hospital (back when Italy was the epicenter in the west) of people silently choking to death in their ventilators. It was absolutely fucking eerie and insane and every time I think of doing something risky, I think about the sound in that video.
Unfortunately in this context, it is illegal to film people in a hospital. I think that's a fair rule but I really would like to have a few videos floating around with no voiceover and no commentary just to scare the shit out of people. I think it would work.
