I wonder how much better Jeanette would have been if her back was 100%? I know when my back started to bother me while playing...I went from a B to a C quickly. Even the days that it wasn't bothering me I would still worry about it on every 9-ball or 8-ball break. There were very few straight pool players in my area in my last five years playing. I had other health issues in the end, but the back is what really made me pack it in for good. Johnnyt
