Not much competition in my resume for this distinction. The best thing I ever did was to provide home care for my dying parents, along with my wife Barbara. They were both dying and wanted to stay at home, so we moved in. Barbara took over my mother's care (cancer) and I assumed the dadly duties (strokes, Alzheimers). It was brutal, exhausting, it consumed our own lives and drove me into prolonged depression and regrets. But one thing I will never regret is being there when they really needed it. In my overdrawn Karma account is one hefty deposit for this difficult period in our lives.
