For millions of years, humans survived without air conditioning. As the summers wore on, we became acclimated to the hot days. Now 82 degrees is considered an inhuman environment. We didn't get AC in my parents house until I was 12, and that was in hot and humid eastern VA. Granted, I appreciate a nice air conditioner on a hot day, but we can get used to anything--and did for millenia up until a few decades ago. In the deep south, men wore seersucker suits and removed their ties before AC. I applaud the Japanese for making these changes. They can come up with attire to match their priorities. Suits made from coolmax (or lightweight wool--the original coolmax), ties with cooling gel inside, it can be done.

O.k. now I'm annoyed. Nixon started the War on Drugs.
Al Gore has his War on Global Warming. Bush has the War on Terror.
Now the Japanese have the War on Air Conditioning.
Therefore, I, Wiredwilly , declare my " War on War. " There it is. My moment in History. Now, would that mean I need to have another War on the phrase " War on War " to challenge the FIRST War in the War on War ? That could of course start a cascading infinity of mirrors effect of ever increasing Wars on War, each abolishing the one prior to itself. Or, what if someone opposes my War on War ? Would they need to start a War on the War on War ? Would the War on the War on War actually be War or would it be Peace because it opposes War ? These are difficult times we live in.
Perhaps I'll move to Japan and repair air-conditioners.

I lived in Japan for ten years. And from personal experience, I wish this was in effect when I was there.

Okay, if Japanese bankers can doff their coats and ties, then US Corporations, it's your turn next. Sorry, but if men in the most formal business in the most formal nation can let loose, Americans have no excuse.
