I've had times when it's felt like I could tell what people were feeling, be it physical or emotional as a form of gathering information. Honestly, I'd -like- to think that it's some sort of advantage, but a few things here and there don't add up and/or generate conflict with this sort of theory. (I.E. Subconscious social processing.) In all honesty, it could simply be a sharp form of subconscious information gathering... But that sounds like longshotting justification (On the other hand, I've known myself to be a strange combination of 'Out there' and sensible). In the grand scheme of things, I don't believe in psionics as generally purported by say... Modern mystics. I do, however, believe that a more scientific, less mystic form of psionics (Closer to a superpower or somesuch.) could arise as a result of some sort of artificially induced change in human biology, electromagnetic implants, ETC. Although this would most likely not be a field of research that would be developed, due to the ethics of such a field of research.
