Here's an idea: there is a part of the brain, somewhere in the subconscious, that knows exactly what is going on in every cell of our bodies.

Somewhere in my head, the first moment that first cancer cell started to multiply inside of me, my brain knew it. And all the choices I made in my life were then being influenced by this knowledge that my subconscious brain had, but my conscious brain was not aware of.

You could even say that is what intuition is. That "gut" feeling is really just your brain knowing what's going on with you, before you, and making decisions accordingly.

And maybe someday they, the scientists and doctors, will find this part of the brain, and be able to hook-up a diagnostic machine to it, and an itemized list of every function, and malfunction, in our bodies will print out (no, not print, we won't be using paper at that point.) Just like a car.

Does this idea already exist? I'm sure it does. I hope they're working on it.
