Only if being around the sound of flowing water had some survival advantage to our ancestors. Kind of a stretch. Especially if you consider crocodiles.MediumTex wrote:It goes back to my comment about the sound of distant flowing water being soothing to people. There may be some subtle evolutionary benefit to people who find that experience soothing and this preference may have created a survival advantage.
The placebo effect is very powerful. Don't ask me how I know this, but you can often successfully treat warts with certain materials that fluoresce under regular UV light. The treatment has no effect other than to make the wart glow a pretty color, but in many cases the warts disappear. The treatment is more effective if the practitioner makes up some scientific-sounding explanation (i.e. "Well, the wavelength of the ultraviolet light makes the magic elixir bind to the wart and sets up harmonic frequencies that destroy the virus"). Along a similar line, in one of the old Whole Earth Catalogs (the proto-internet), a successful treatment for plantar warts was described as consisting of "voodoo and a Swiss Army Knife".
But almost invariably a scientific explanation will ultimately explain the phenomenon. Eating green leafy vegetables makes me feel better, smell better, and look better. What subtle property makes that happen? Oh, wait. There are vitamins in those things. Difficult to discover and quantify, but ultimately quantifiable.MediumTex wrote:The electrical discharge theory might actually just be the explanation offered by a civilization accustomed to such technical explanations when the truth is more subtle and harder to quantify.
If there is something to grounding, I would think that electronics workers who are tethered to grounding straps all day would be the happiest, healthiest people on earth.
