Many of my friends and their friends are doctors.
Recently, a chap, whose company was embroiled in an international scandal because of poor craftsmanship by outside "contractors" told a TRUE but, horrific tale.
Made very short...it goes like this:
A man who had been seeing a back-specialist became frustrated with his own individual "lack of progress." He went to a chiropractor and acheived immediate relief and satisfaction. He continued with the chiropractor through multiple visits and abandoned his back-specialist.........UNTIL.......the chiroprator "made an adjustment" which shot one of his spinal disks out from his vertibae like a pumpkin seed in the hands of child. The chiroprator confided to the patient that he was "now beyond the abilities of the "chiropractic science."
