Allow me to introduce myself.
I began medical school at 36 years old and have loved every minute of medical learning and practice for over 36 years. After 18 years in the Navy including SEAL Team operations, followed by 18 years as an Army physician that included international combat deployments with the 82nd Airborne Division in Iraq and the famed DELTA Force special operators, I retired from the military as a Medical Corps Colonel, and entered civilian private practice.
I have worked in military and civilian hospitals doing inpatient and critical care medicine for many years. I met patients in the emergency room, admitted them to the hospital and intensive care wards, and managed them overnight.
There are several differences in how the civilian medical world operates. Most of these differences revolve around civilian expensive and defensive medicine practiced to avoid malpractice lawsuits.
