Yup! This is why whenever a fat gets sat next to me and I can't slam the arm rest down (or they stink), I vocally request to the flight attendant to be moved because I feel unsafe and I am claustrophobic. Fats are dangerous on a plane in my opinion because they can't react fast enough in emergencies and they'll clog up the aisle with their fat in the event of having to get off a plane in an emergency. They're also selfish and would gladly shove over old ladies and shit to try and save themselves.
