No easy answers
In the latest (surprisingly non-sexual) Weird Japan News, it seems there is a problem with people who are so afraid of the world that they become hermits, shutting themselves up in their own bedrooms. Something like a half a percent of all Japanese apparently fall into this category, which in the US would be like a million people or more.
I was going to recommend that they get outside, take walks, and maybe take a nice relaxing dip in the hot tub every now and then. But maybe that's not such a good idea, either. Maybe a hobby? Something constructive?
Let me know if you have any solutions we can pass along to our Japanese friends.
