I spent a lot of time this weekend reading the latest Acid Logic. The "All Politics" issue covers Fox News, Bush's penis size and has an interesting, if rambling, discussion of the most bad ass redneck on the planet, Fred Thompson.
If you are not so into the political scene, My So-called Penis is a hilarious view into the mind of a man who has obviously misplaced his medication.
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.
