The 75 year old co-worker, who would not retire ("I need to stay busy and why do volunteer work when I can get paid"), who was forced to go part-time after wetting chairs. She was a floater, filling in during vacations and the receptionist's breaktimes and lunchtime, and had a bladder problem. She told HR she had gotten it under control, but not true. So she worked 3 hour days until she retired at age 78 because of other health problems. People learned to look before they sat.
