I left EMS 27 years ago but then moved into medical admin and management for 15 years. Quit that 10 years ago and people you work with will still search you out for medical advice and will be dragged by the arm to someone with a medical emergency in the workplace. Once a medic, always a medic. You just thought you left it behind. I still keep a substantial kit and have had occasion to use it, unfortunately.

I didn't do 20 active duty,but I did 8. It was enough, but all together I did 24 years in hospitals. clinics and independent duty in a variety of roles.

Best of luck in whatever you do...., Doc. (sound familiar)
