Here we are in the middle of Kuuru Bizu. Cool what? you say. There is nothing cool about the hot and humid summer in Japan. Perhaps they meant "cool busy" as in busy trying to find someplace cool to hang out.
Cool Biz is the government's campaign to turn down the air conditioning in offices to save energy and the environment, although the environment seems to be a bit heartless in caring about us. Cool Biz also aims to get business men to cast off jackets and neck ties in order to cool the body temperature by two degrees.
If taking off a jacket and tie can cool the body by two degrees, think of how much cooler it would be with nothing on at all. Don't laugh — you don't see tribes in Borneo or the Amazon wearing suits do you? And what about socks? Socks alone must be responsible for two degrees (one degree on each foot), and underwear would have to account for another degree. So as often as I can, I opt for a bikini. When even that gets too hot, I jump in the sea, or go for a boat ride.
