...in the Old Testament Book of Leviticus, we're told it is wrong for a man to be with another man. However, within the same book we are also told that it is wrong to eat pork. If Fundamentalists use the Leviticus verses, simply ask them when was the last time they had bacon. According to the same Old Testament book that condemns the practice of homosexuality, they would also be condemned to hell for eating a BLT sandwich. However, they would not be committing sin if they still owned slaves, since Leviticus tells us such activity is okay. Think the Fundamentalists will agree with that?
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.
