I use to work at Flushing hospital in Queens New York in the mid 1980s during the height of the AIDS epidemic and I would just about everyday have to wrap up the AIDS corpses - Tape up the hand and legs, put them in a bag, then in the freezer. Never affected me, it was like putting away mannequins.
Then I would get the victims from the ER. One guy once had his face chainsawed almost in half. Then I had a car accident where 3 kids died. They were like dolls, and when I closed the freezer door I broke down and cried to the point of almost having a seizure. Nothing affected me until that.
