Skin depth has the resistivity of the "conductor" factored in and
humans, not being the best conductors in the world have a
consequently large skin depth. The other important variable is
frequency, skin depth being inversely proportional to the square root.
Engineering texts by Terman et al have formulae for skin depth.
