Things I didn't know

Many of which I learned this evening, from Britt Bergman and Jon Black's Very Little Known Facts blog:

• After the globalization of [Ping Pong,] the sport they helped popularize, Siamese twins Chang and Eng died of grief.
  
• Wild horses can regenerate a leg if the herd has been culled too low.
  
• Ceiling fans cause more finger and lower arm amputations each year than all the wars in the world combined.

God, if only blogs had been around when I was in college, I might have emerged smarter. I might even know the difference between Australia and New Zealand.
