There is this guy who only has one eye. He goes to a doctor who recommends a glass replacement. The guy cannot afford it, so the doctor fits one made one out of wood. He is really self conscious about it and becomes a bit of a recluse.
One day his friend sets him up on a date. His friend warns him that the girl is a hunchback and is real sensitive about it, so he should not draw attention to it. Knowing how he feels about this wooden eye, he says he understands.
When they meet at a club, he goes up to her and says, "Want to dance?"
She looks really excited and says, "Would I!"
The guy get angry and yells "Hunchback! Hunchback!" then leaves.
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.
