As an incidental, one of the Blade movies showed a vampire-run “blood farm” where braindead humans were hooked up to tubes (and, it seemed, hung up in giant vaccuum-sealed plastic bags similar to the ones used to store comic books) to keep them fed and to constantly bleed them. I remembering wondering at the time why all the “cattle” were put in storage fully dressed. Surely clothing on what is effectively a bed-ridden comatose patient poses a risk of bedsores, infections, and blood-poisoning, with horrific real-life cases in which an immobile obese person’s skin cells grew into the fabric’s weave as case in point.
I have an issue of WWN that shows Hitler’s autopsy photos, and turns out… he was actually a she.
It’s not the fabric that’s the problem in those cases, it’s the constant unrelieved pressure. The pressure/immobility gives you bedsores/pressure ulcers, which get all runny and infected if you don’t a) move the patient to relieve the pressure, and b) clean off any dead tissue. (Actually, they can get infected even when you do those things–it’s what killed Christopher Reeve.)
