I've got a quickie... It will require pure guesswork on your part, but you'll be amazed at the answer.
In Japan, bicycles are one of the most common forms of transportation. Kids ride them to school, housewives ride them to the supermarket, and of course, people ride them for pleasure too. The most common are 'market bikes' like the nasty old lady in The Wizard of Oz rode, with a basket in front, and
you find literally hundreds of these parked outside all train stations in Japan. And lots of bikes get stolen every day.
Question: What 'group' of people are responsible for 80% of all bicycle thefts in Japan?
For 'group' you can choose type, age, gender, Nationality, religion, hair color, clothing designer, etc., etc. ANY grouping. They steal 80% of all the bicycles...
Who are they?
