Think about it: What did you learn in 2007? For many of us, we learned lessons about ourselves, our lives, our place in this world and so forth. But the world as a whole learned a thing or two as well. The BBC recently compiled this fascinating list of 100 things we didn't know last year.

In particular, there were several interesting things we learned on the health front, like:

• Adding milk to tea takes away any healthy benefit that the tea had.
  
• 99% of bacteria on dishcloths is destroyed by two minutes in the microwave.
  
• Two cups of spearmint tea a day will curb extra hair growth in women.
  
• The average duvet is home to 20,000 dust mites. Ick.
  
• Most crematoriums are having to renovate their facilities to accommodate increasingly obese corpses.
• Anthony and Cleopatra were not nearly as attractive as Hollywood would have us believe (Ok, not health-related but interesting!)

There's lots more (including the astounding fact that there is cell-phone reception on Mount Everest,) so check it out!
