You are correct. Sorry for the omission. The reason I think it's amazing isn't because of our capacity to move objects. I'm a computer nerd. My PC draws hundreds of watts. Humans beings are constantly processing genetic information (in a way) and our brains are capable of some impressive processing as well. All this in under 100 watts impresses me.
The human brain draws only about 20 watts according to what I've read elsewhere on the net. Anyway, wouldn't it be nice if we could just plug in to a wall outlet and save having to buy all those carbohydrates? I need to invent an electric glucose generator. Of course, I'm sure it's been tried before. --- James Frysinger <[EMAIL PROTECTED]> wrote: > Right you are, David.
