Honestly.. I rode motorcycles for years in the Texas summers and winters.. and they were not equipped with air conditioning (or heat)... and when i worked patrol, I NEVER used the air conditioner in the car in the summer, even with all the equipment i was having to carry/wear. My position was if I was chasing some tick-turd... I wasn't going to have AC blowing on me then.... and with the windows of the patrol unit rolled up.. I couldn't hear ambient noises.
Even 20 years later, it still is a "position" I take.. and I constantly have the spouse bitching at me because it is 100° outside, and I'm riding with the windows rolled down.. she wants that AC on high/recirculate.
The sad thing is.. MUCH of current society is in that very position.. they can't deal with the heat.
