I have personally worked fires where due to smoke inhalation people have done things and or acts that they were unaware of and were not what you would think a normal person would do. In one instance a retired NFL player who left something on the stove tried to get out of the back door that was key locked from the inside with bars over the door window after struggling with the door for several minutes and not being able to get it open or knock the bars out having cut his arms badly on the glass and with witnesses trying to help him get the door open turned around and walked 20 to so feet down a hallway went back into his bedroom where he was napping at the time of the fire and got back into bed where he was found by the first in FF dead from smoke inhalation. The witnesses said one second he was fighting to get out and the next he just walked away from the door.
