I'm on your side, all the way. The more you know, the better off you are when it comes to your health. the head in the sand approach leaves you open for medical issues to turn into emergencies unnecessarily. That is not the way to go.
You are your own manger of your life, and without your attention, and involvement little things can become problematic. These protocols for the procedures needed as we age are there for a reason, and should be followed.
I tried that ostrich approach when I was younger, and ignored the warnings my doctor gave me about my high blood pressure, after all, I was in my 20's, early 30's...right in the middle of my career, child rearing, and strong as an ox, healthy as could be! At the age of 43, I had 4 strokes, kidney failure and damaged my heart, my retinas, and was left to re-learn how to walk, talk, think, and to this day need help to manage the simplest things, like bills, housework, medications, driving, and more.
This is certainly not to say that everyone will have such drastic outcomes, but it is a my story. These days, I am totally disabled, and see doctors several times each week. To top it off, I was just struck with endometriosis, which is ruining what is left of my life.
Stick with your guns, and make use of the amazing advances that have been made in medicine...If I would have learned that earlier, I could have likely avoided all this! The routine tests are a piece of cake compared to the alternative.
