Oh I know, not to mention the damage they do to nurses who have to try and lift them. They take almost twice as much time as a normal sized person from the nurses too, because a big part of their job is skin inspection and dealing with skin conditions all of which fats have more of. I actually found this study while researching dangers obese patients cause to the nurses that have to move them.  The only part of this study that is indisputably correct is: yes, they definitely die earlier.
