Virginia, I also taught for 3 years before retirement. I have been a registerd nurse for 20yrs, till my back gave out, then an OHS and Workers Compensation Claims manager for 20years in a variety of industries, then teaching OHS & Rehab for Managers for 3 years at ac college. I enjoyed teaching adults who actually wanted to learn. DH was a high school teacher for 43 years before he also had to retire due to ill health (Virus attacked his balance centre in the brain).
