I arrived in Great Lakes Navy Boot Camp in 1966; soon standing naked shoulder to shoulder in a line of 50 guys as one corpsman walked in front checking my private parts and one in back administering a gigantic penicillin shot to the buttocks. Before leaving to a carrier in the Sea of Japan, I stood in a long line to receive air gun shots in both arms and as blood dripped off my fingers wondered if 12 shots in 20 minutes might have side effects.
Corpsmen served in combat with the Marines in VN and assigned to Sick Bay on ships. The lower ranks had boot camp training then minimum tech school before assignments in the field.
Military medicine may be the precursor of things to come because the Military knows about efficient medicine and Civilians are copying; allowing pharmacies to give shots and routine checkups. EMT can handle road side emergencies. As the injury becomes more complex, the Doctors take over. Some Docs are in other countries viewing the patient on Skype and diagnosing with Watson Medical Computer.
Recently, I paid $300 to get on a medical bus at CVS and nurses performed $2000 value tests for stroke and heart attack alert. Michael Moore documentary SICKO lets us view how other countries are providing reasonably cost effective services.
Conclusion: A CNA course (Certified Nurse Associate) takes 6 weeks to complete. I may send one of the grand kids and call them for minor emergencies. I would need to text and wait a day for response. The Military is efficient and the VA hospital will get their act together sooner or later. I plan to fabricate some dog tags if cannot find my old ones. Join the military for a few years and get the "free" medical plans Bernie is promising.
