I lost three teeth in the last month or so. A problematic back molar eventually worked itself loose. More problematic, one of my two top front teeth hung loose prompting a cosmetic necessity of replacement, ... and while at the dentist I decided to eliminate a space from an earlier fall out. In the process of replacing my old bottom front teeth caps an additional tooth came out. Forgive this graphic explanation (more than you probably care to know).
My point being... the misfortune of aging pounces, and we have only so much we can do to prevent the onslaught. This belligerence of nature is terrifying, and I find myself scrimmaging for philosophical insights to shield from depression. Sure wish I had some god to offer to. Perhaps the inevitable sacrifice is our own human form, as in Christ on his cross. Nobody gets out of here alive, and seldom in good form. The bones in our necklace at death are often our own.
