Things learned

Over the weekend, I learned (via some ABC Radio National listening):

*  China is trying hard to break into the international film market, but they are having trouble given that they want their films to be both nationalist and appeal to other audiences.  (Their film industry is under close government control.)   God knows, with an awful attempt at a blockbuster like The Wandering Earth, they do have a way to go.

*  The world is running out of sand for concrete.  Apparently, you can't just use any sand (like from a desert), and hence too many countries are ruining too many rivers and lakes in dredging up sand.  Australia also apparently sold sand to Dubai for the construction of the Burj Khalifa.   Didn't know that.

* Cricket boxes, for the protection of male genitalia, don't seem to undergo much in the way of testing for efficacy.  And lots of sports result can result in serious injury with cycling (if I recall correctly) at the top of the list for numbers of injuries.   It's a good reason not to get into sport, if you ask me.
