[LINK] tDCS

[stephen at melbpc.org.au]

To me, this is interesting.

Two electrodes (possibly, just two bare wires) placed against the head
just above and to the front of the ears and maybe to a 12 volt battery
for ten minutes may well significantly increase brainpower, apparently.

Will be interesting to track follow-up research. If these findings are
replicated, a patented $5 black-box might make one many, many millions
if it also works, as demonstrated, via a plug-pack electrical waveform.

Maybe :) Anyway, for those doing Earth Hour tonight, don't worry, I'll
take up the slack sitting reading by the light of the open fridge door.

Cheers,
Stephen
