Or maybe even a Keto Diet. Getting rid of all those carbohydrates the corporate drug pushers have pushed on us brings on a whole new attitude it feels to me. I kind of being forced on it myself. I contracted MRSA (a form of antibiotic-resistant bacterial infection). The low carb diet (that pre-agricultural diet of hunter-gatherers) kind of just stops the stuff in its tracks.
Though it's good for a lot of other things besides that, many medical problems today are caused by the high-carb diet. One of the best things I find about this diet is how it calms down your whole life and gets you clear thinking. It works well whether your young or old and the effects are subtle and you can feel how it's working in about three days
There is a movie called "The Magic Pill" on Netflix or Amazon Prime that blew my mind when I saw how well it worked on a sad little autistic girl. I know this post is a little off the subject but if you can understand how a lot of these neuroses are acquired by our screwed up diets it would make sense on the subject.
At Fifty-nine and mostly an introvert, it figures to me knowing too much about oneself can be perilous (but not to worry it probably can never happen)
