I have no idea how many I've had. Whatever was required for me in order to attend public school back throughout the 70's. Then again in the military, which I paid no attention how many they gave me. I just know it was a lot when I served. Since then, I haven't had any others, except for whatever pain drugs or whatever they use to knock a person out for surgeries, either through IVs and/or an injection for my medical type emergencies of the past, and perhaps when I was treated for a histoplasmoses infection in my chest. Other than that, I have not volunteered for any immunization type shot from anyone ever since, and all of that happened when I was much younger.
I try my best to stay away from doctors and/or hospitals and simply practice good health habits as best as I can these days here at home. Very seldom do I ever get sick other then the regular basic seasonal type allergies or sinus issues once in while. that's about it.
Back in 92, I had one of the best heart surgeons in the county at the time ask me if I was a professional athlete when I was recovering from pretty darn serious auto wrench that wasn't my fault, that nearly killed me on the spot when it happened. The doctor induced me into a coma for 10 days before he even worked on me due to all the server swelling around most of my vital organs and the head. He was amazed on how quickly I recovered from those injuries, both internally and external. Took me about a year in a half to recover to the point where I felt I was basically back to my normal self, however, I still suffer from it today. Arthritis mainly in my chest and back area, where all my ribs connect to my vertebrae. Anytime I over do it, physical work wise or any real bitter cold temperatures, get to me pretty bad. When it happens, it's like someone punched me in the chest and then I suffer what is like, the wind was knock out of me, or like breathing out of drinking straw, because my ribs don't expand normally trying to take a breath when it happens. That too only happens once in while nowadays, and I try to look out for it, trying to be as proactive about it as best as I can. Any decent physical activity in the summer or warmer months isn't nearly as bad for me, so, you can say that I do prefer sun heat or warmer seasons over the winter months these days. It's one of the reasons why I love being in the woods from open-n-day hunting season until I'm forced to pull out my heavy winter gear to keep me protected from those colder outdoor temps.
Sorry if I went a bit over board here, but that's the jest pretty much of all my medical history, right there in a nutshell, for all to read
