Apparently Common Knowledge In Japan: pickled plums are the ultimate hangover cure; fish is good for your skin; coffee makes you smarter (I suspect this of being the result of someone’s Really Good marketing campaign); milk makes kids grow bigger (probably an American company’s marketing campaign); you shouldn’t take a bath when you’re sick.
I think I’ve figured out the origin of the last one. People get sick more in cold weather, people in Japan mostly bathe at night, and Japanese apartments mostly aren’t heated very well. I think it would be more effective if they came up with some superstition regarding not bathing in the winter.
The point of this post is to bitch that my apartment’s all cold and I showered last night and now I’ve got a cold or something.
