Chlamydia is one of the most common STDs, particularly among college-aged men and women. Fortunately, unlike in the old days, it's now quite easy and painless to get tested and treated for a chlamydia infection.

I've only been there for a few months, but it seems to me that Japan gets earthquakes very often. From 1 to 4 quakes a month, it depends. Every time I felt an earthquake I was in Tokyo. It usually doesn't last long (10 to 30 seconds) and it doesn't get that shaky, so it's cool. Besides, most Japanese are taught how to react when it happens. I was in Tokyo during the March 11th event.
