Yes, 85 is well beyond "constant sweating even when not moving or doing anything" temperatures for me, and I wouldn't want to be in a room of coworkers doing the same either. 78 would be at the edge of idle sweating.
People who complain about having to put on a sweater have no idea how miserable it is for those of us who have to sit for 8+ hours in an environment sweating profusely when it gets too hot.
This is why office AC is the way it is. You can put on a sweater. I cannot take off my skin.
Like fucking roasting all day...
