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.
