My coworker had the brilliant idea to book a load of filter changes in the top of a glass building where the ventilation rooms are hardly ventilated (ironic). So I was stuck crawling around in ventilation ducts and hauling stuff up and down stairs and ladders in protective gear in 35 degree heat. My gloves had half a deciliter of sweat each in them when I took them off.

If only it had been the day before when it was pissing rain, but no, the weather has to be an asshole like that.
