Here in Japan, the most common delay reason I see on the signs is "passenger injury". I think we all understand that they don't mean it's a grandma who fell over and hurt her leg...
Apparently Japan has an abnormally high suicide rate too. It ranks 10th in the world according to wikipedia: http://en.wikipedia.org/wiki/List_of_countries_by_suicide_ra... while france is 26th.
I would call a single suicide an abnormally high rate but I digress...
