I had a car wreck that almost killed me in '82 and when I got around 45-50 my back started bothering me and I had to start going to a Chiropractor. An Orthopedic surgeon put me in an MRI and said I have Osteo Arthritis in my spine and nothing can be done about it. It came from that car wreck.
He can do just what I do...use his desk top in the morning and then in the evening when he gets back! You ever notice how they come up with a new improved one every year and the cattle keep falling for it? That kind of money on something that unnecessary is crazy! ( with the exception of a few jobs that need them.)
