"heart beat pulses at 60hz" I would not rely on that... On average humans, 72 beats a minute, higher if you smoke and drink coffee non-stop like myself.

Far cry from 60 cycles, a second.
Also be wary of placing meter probes on the body, many have voltage that could be not cool going across the heart. Especially those used to check ground resistance.
Anyway, I think this sticker is intended for situations where the the gen set is not part of a building ground, and not perminatly bonded to the neutral, making it a seperately drived system. It would then require its own rod(s) at 25 ohms or less. Or, if it were a stand alone power source.
Tied to the buildings ground system (Bonded neutrals and all), and with a EGC sized for it, you would not need a seperate rod at all. Making said sticker a superphilus decoration.
