Do you think it is possible to have electrical powers?

don't think it will be possible even if one can find a certain 'switch' to turn on the heat, so to say. body sells and nerve cells are not made to 'handle' high voltage and/or current, I think. I am not a specialist in terms of body cells and their composition and functions, but it's a fair guess and there is no 'switch' to alter all body cells to make more durable in terms of electrical conductivity.
