Wow! I hope the body knows what it's doing, messing around with all this chemistry. At least, I hope it is better than me in the 60's with little explosions that would make my family freak. They preferred that I take my experiments outside.
I also hope that I'm providing my body with all the nutrients that it needs for such chemistry.
We are not really fooling around with the chemistry, we are providing the body with what it needs to do its job properly. No different than getting a lot of the same stuff through diet, which also provides things our body needs to function. But the body is not designed to deal with things like antacids, acid blockers, endocrine disruptors, etc. We are merely giving the body some tools to help deal with the problems that these and other things that screw up the body's natural processes.
