Many folks seem to categorize their environmental conditions based on how they feel. In winter, I find myself using the following scale.
Not Bad - It's somewhat comfortable out here
A Bit Brisk - It was Not Bad, but then the wind came up and I want to go inside
Cold - Yeah, it's cold out here
Very Cold - I'd like to crawl inside the freezer to warm up
Freezing - The lucky parts are going numb
Freakishly Cold - Time is slowing down
Are You Kidding Me? - I'm shivering so hard, I just fell out of my skin
Relative Zero - It may not be Absolute Zero, but you can see it from here
Untitled - My brain has frozen and fallen off
I've spent too much time in the lower end of that scale.
