I salute you guys who still posses your math skills. I lost a large portion of mine years ago when I had a severe blood flow discrepancy to my brain that I didn't even realize was happening until one day I woke up and thought I was having a heart attack. It turned out to be 90% Arterial blockage to my LAD the artery that supplies the Heart caused by scar tissue build up pressing on the outside of the artery which was most likely caused by a missed fragment of Shrapnel dating circa 1971 or 2 . A stint solved the problem but I had already spent nearly a year without a decent new coherent design thought. That was about the time I decided it best that I retire and put my shingle in a drawer
Toolmaker 51 Never underestimate the power of "n" when looking for "X" or you will wind up having to cosign the tangent.
