Peter, yet another cosmic connection: on April 1, 1966, I went under the knife for "exploratory surgery" concerning a bump in my leg. Six hours later they had removed a tumor, along with 85% of my calf muscle. Back in those days, (though nobody told me about at the time), my parents had to wait a week for the lab report to find out whether or not it was malignant and I'd, at the minimum, be losing the leg. Thankfully, it was benign and other than losing my speed running, and always wearing out my right heel first, I've had no further problems in that regard. We should all strive to fully appreciate whatever we have while we're here.
