On January 1, BBC News posted their list of 100 things we didn't know last year, a fun list of tidbits from around the world. By each tidbit, a "more details" link leads to a BBC story explaining it. Here are some favorites:

16. Chimpanzees make their own spears for hunting.

20. More than half (52%) of smokers haven't told their parents about their habit.

34. Kryptonite exists.

49. CDs were nearly called mini-racks.

62. Until the late 1990s, the RAF's nuclear bombs could be activated using a bicycle lock key.
