I know what you mean, I got too comfortable with central air in my apartment. So now if it gets over 75 in my room I usually just sleep in the basement's (fully furnished) guest bedroom which is always really cool.
I thought about moving my headphone setup to the basement lounge/game room just because it's so cool. But meh laziness (I was only home a month).
I can't stand the cold, usually keep it at 78-80
