Yeah. Before fats took over only people with actual medical problems used them (people with only one lung, lungcancer, 100-year old ladies with like zero lung function, etc), as well as for emergencies in hospitals (heart attacks, strokes, surgeries etc). Now the major users seem to be fats. Fats are also the ones who complain the most from what I can tell. "Wuaaaah it's uncomfortable" "Wuaaah I can't eat with it in the way!"
