Murder on the Hour

While dealing with the young lady covered in gold paint who was participating in a James Bond Goldfinger fantasy with her James Bond role playing boyfriend, Dr. Sloan correctly states that suffocating because the body can't breath through the paint is a movie created myth. However, the young lady is having trouble breathing and he states "She's suffocating." Dr. Sloan then explains that it's due to the fact that the paint doesn't allow the chest or stomach to expand when it dries. The amount of paint on the patient is covered in is very light, and would never prevent one from inhaling even of it were heavily applied.
