I don't know if it is the weather or not, but these forums have been generally unhelpful lately and lots of snide remarks and irrelevant replies. Maybe the winter has gotten people all grumpy lately.
Personally, I only reply if I think I can help, and try to focus on only the parts that I can help with. Or, prompt someone to clarify their questions. With this particular question, I was asked before to design a device that sent current through the body safely (not data), so I did some research on the subject. There are a ton of different factors that come into play with anything that involves the body and electricity right down to electrode choice.
