Hey there cool bits on info. 🤔
I've done a little study in some of these areas that you have touched on. An interesting thing about the placebo affect is the frequency associated to different thoughts, positive vs negative etc.
But also that holding a medication next to the head and a sound wave frequency is played so the brain pattern respond to the frequency of the medication, shows results the same if the medication was digested.
I wish I had kept the study when I read it, so I could link it here. But there definitely is a lot more happening in our world then we generally consider. 😉
