Everybody is in suits, with high collars and neckties. The ladies all wear long skirts, and button shoes.

Maybe it was diet. People had a lower metabolic rate then because food was expensive, and less varied. I know when some of my Silicon Valley colleagues went to China to install a satellite reconnaissance system, (hey, don't blame me, it was the Reagan administration) they remarked that everyone wore woolen Mao suits, buttoned up all the way, and woolen caps in the hot summer sun. They were fascinated by the crazy Americans playing softball in shorts and t-shirts.

I remember growing up without A/C in Florida and the heat was so bad I would often wake up in the middle of the night, (my bed was pushed against an open window) go take a cold shower, dry off, and by the time I got back to bed I was drenched with sweat again.
