I had a triple bypass on April 25th and spent 6 days in the hospital. I am now recuperating at home! My problems began last month when i tried to get medical clearance for back surgery and a stress test showed that I had blockage in 3 arteries of over 90%. The thing I hate worse is that a week before the surgery my new Grizzly G4003G Gunsmith lathe arrived and I have yet to use it!!
