I just talked to embalmer Richard Hirschman about the reaction from Died Suddenly

Embalmer Richard Richard related the story of people in a hospital talking about the movie. One of the doctors said, “This is just a conspiracy theory.” Another doctor said, “No it isn’t. I know one of the embalmers and I’ve seen this first hand. It’s legit.” The response was, “We aren’t allowed to talk about that” and then they changed the topic.
