I mean, just on it's face ....70 year old man who lived a rough life and had a previous near fatal heath scare needing a procedure done on his heart...tends to make it sound more serious than Conrad wants to let on. And I get it, he doesn't want a circus in the hospital and is trying to downplay things to keep a lid on it.
Not sure why everyone is so viscerally angry at Satin though, unless it's a general "he worked for TMZ and they are shit so he must be shit too". I don't recall him personally lying about something.
