I drive a 10-year-old car. In terms of lifespan, my body is about the same age as my vehicle. I am living what Oprah calls “my best life” wen I treat my body in the same way I treat my car. Wash it regularly. No waxing. Don’t think about it overmuch. Those dings and scratches? Let them be. If something breaks, get it fixed. When the car is parked, forget the car.
