A few years back I was visiting with a veteran colleague. She was much older than me, well past the age when most people retire, yet she was still working and volunteering and enjoying every minute of life. I asked how she managed to stay so productive. She laughed: âIf you are going to burn the candle at both ends, you just have to get more wax.â Some people seem to have an inexhaustible supply of wax. But they are the exceptional few, and there are fewer each year. Workplace statistics indicate we are a nation full of people running out of wax.
