11/11   How come people in big crowded cities in Japan don't live in high-rise
        buildings like those in Hong Kong?  First I thought it's because of
        earthquakes, but then they already know how to build high-rise hotels
        and office buildings in those cities.
        \_ 1) Earthquakes.  Sure, Japanese engineers can build some amazingly
           earthquake-resistant buildings, but those kinds of buildings are
           terribly expensive to build, so why use them for housing when you
           can charge an arm and a leg for them as hotels?  2) There's actually
           more room in Japan per capita than there is in Hong Kong.
