Yesterday I completed my annual long-distance run. My reference point for this activity is a practice that I read about that is followed on a small Pacific island where the old folks annually are obliged to shinny up a palm tree, and told to hang on.
Meanwhile the kids gather at the bottom and shake like hell. The old folks who are able to endure this shaking are vouchsafed another year of life. Those not capable are referred to the local hospice for end-of-life care. Yesterday was my one-year survival test. I hung on.
