Like I said, I took those tests for the benefit of the doctors and family. Not myself. I would rather not deal with nagging, if you know what I mean. I do understand the point you are trying to make about coming up with ways of making our own diagnostic health tests. Actually I have one...Iridology. It has worked well for me. I can tell if something I'm doing with my health is benefiting me or not. And yes, the iris can change very quickly. I'm just not happy with some of the other things you have mentioned.
Like I said before, I worked hard and learned what I wanted to learn and stuck it in my belt and no one can take it away from me. It will serve mankind well in the future if everyone learns a skill...but I don't really want to learn every skill that is out there. Nor am I gifted to do so.
