They didn't wander, they travelled through the wire that's connected from your body to the ground.

.. however, they can only travel towards positively charged objects, which they then proceed to make less positive. Note that at no point do they attempt to quantify these alleged electrons, measure a potential difference between the body and ground, or the magnitude of current flow in the wire. Moreover, free electrons do not float about in solutions. They're usually carried about by negative ions. If you can change that the battery industry would be very interested to hear about it. Edit: I'm wrong about not quantifying! > Electrostatic charge was measured on the skin at the region of the vastus lateralis via an electrostatic voltmeter (ESVM 1000, Wolfgang Warmbier, Germany). The pilot study revealed values of -0.2 ± 0.1 V vs. -81.9 ± 25.6 V (P < 0.001) in the grounded vs. sham-grounded situation clearly demonstrating the effects of grounding via the conductive sheet. .. but there's another problem. Humans are conductive. Even if there's a net charge on your surface, the charge inside you must be zero in conventional electrostatics. Also, some of those measured values are negative, so if this alleged effect is tied to electrons, those people are made "worse" by grounding them!

  Is an electron a particle? You're expecting it to behave like a particle, but it's not a particle. This study demonstrates that grounding increases muscle recovery time. We definitely need to learn more (and they highlight some potential explanations) but it's not trying to prove anything about electrons.

    From the paper: > the main hypothesis about earthing is based on the connection to the surface of the Earth, which is satiated with free electrons. This indirect or direct contact with the Earth enables “mobile” electrons to migrate into the body (it then goes into anti-oxidants etc.) This hypothesis has remarkable implications for ordinary chemistry, if it were true. I don't see why wave-particle duality would be relevant here, do you care to explain?

The wandering of electrons is called electric current. The article claims the earth crust would be saturated with free electrons - thus having a fairly detectable (I imagine) negative load. Which it doesn't have. And even if it had, those free electrons still wouldn't wander without having a reason to, say the body got itself a positive load by friction or whatever. Then the transfer would be immediate, a hopefully small shock and done, no more wandering (scatter wouldn't matter at such distances anyway). Shortly put: it's an interesting study from the physiology statistics point of view, but the physics interpretation doesn't hold.
