I'm back from my trip to Tokyo, and thanks very much to all of you out there who provided helpful information that made our trip easier and more enjoyable (and saved us some money too).
My wife and I have a question that someone out there might answer.
We kept seeing people in Tokyo, in the street, on the subway, etc., wearing surgical masks over their faces. The polution didn't seem bad, so we wondered what the masks are for?
Is it because they are scared of catching someone else's virus?
Or do the people have an illness and they're trying to prevent it from spreading to other people?
