Sorry to hear about your problem Newt,as we all get older there's all manner of things that can go wrong with us,cancer has been our burden in the family with my granddad,my grandma and my father all dying of lung cancer,I did the wise thing of packing up smoking in 98 but as a young man I took several tumbles from motorcycles,to date I've broken my left leg 3 times,my right leg twice,left arm and I've lost count how many times I've broken my ribs(no laughing matter).Now I wait to see what goes wrong in the later stages of my life,
