well... I'm creative... I can imagine lots of faces and real people's faces, and their body... move them around and stuff, animate them... side effect of too much thinking, another thing is that I can see myself from diff angles in realtime, like a out of body experience and half here and there. It's hard to explain. But my point is, I always had this keen sense, I just wanna see if it improves when I PR. But I don't doubt that PR is helping your skill of recalling faces.
