By the way (and I hate to even mention this for fear that the idea may go wafting off into the ether), but the lower back problem comes and goes as a result of a scoliosis (a spinal curvature caused by weakened muscles on the right side of my spine as a result of polio at the age of two).

Because I have had back problems off and on all my life, according to current health insurance company practices, at any time, my insurance company could declare my back problem a "pre-existing condition" and refuse to pay for further treatment.

Lovely, wot!??
