Agreed on our blood chemistry. Also for certain types of “dowsing” for metal pipes or even plastic pipes in some soils, although that is the earths electromagnetic field that folks respond to. The wands (metal) are just the indicator dial of what one’s body is picking up. It worked once for me - but usually it doesn’t. While some folks can do it easily all the time. Maybe I need to drink more Gaterade with the electrolytes!?
I’ve heard people say that sleeping with their head to the north helps with their sense of direction.
Had an older friend (passed on for several years) who was a dowser. He tried teaching it to me but I just didn’t have the knack. He however could find water like nobody’s business.
“electrolytes” Witty... lol
More iron maybe? :)
