Over at The Wisdom of the Illiterati, there is a link to a map game that tests your knowledge of North African and Middle Eastern countries. I used to read the Hammond World Atlas for enjoyment as a kid, and I still missed most of North West Africa. Got all of the Middle East.

I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
