When Live People Turn Dead.

Won't tell you how my train of thought got to this station...well okay, I will.
I've been watching clips from the show Scrubs on the net tonight. In one of the clips they lost 4 patients in one day, and they show the deaths in this sad little montage. In some cases it was flatlines, in others they reluctantly stopped trying to save the patient. One of the clips showed them pulling all the sensors off of the patient, which at that point had ceased to be a person and had instead become a corpse.
It got me thinking about that line between life and death. How in one moment a person is living and breathing, and in the next they aren't. How do you measure that moment? How fast does it happen?
It got me thinking about the infinite again. The smallness of that space between living and dead is inconceivable. It's non-existent in fact. One either is or isn't.
Anyway, the other thing it got me thinking of was my mom. She died in a hospital years back. She had sensors taped all over her. It didn't occur to me until tonight that somebody pulled those sensors off when she made that leap from was to wasn't. It must be a strange feeling to be that person.
