I'm a retired Marine Biologist who, in the mid 80s, tried to switch careers. I was enrolled in the Exercise Physiology Program at Purdue University-- but left with a Masters degree. In my younger days I was competitive Olympic style Weightlifter where i earned a Master of sport rating. After retiring as a biologist I work part time as a Research Assistant at two hospitals. Then I became an elementary school Physical Education Assistant--and at 70 became a certified K-12 Physical education teacher in the State of Florida. The past 2+ years I have worked as a part-time Personal trainer and Group fitness instructor at a YMCA in St Petersburg, FL
