Will someone here teach me something I don't already know?

For efficiency's sake, first make me a list of things you already know.

Your brain can transfer the correct color image from a black and white photo. You have to stare a a black dot for one minute, then look at a black and white photo, while continuing to stare at the black dot. The image will look like a color photo , all colors properly placed. Your brain , from conditioning, knows what color the black and white photo is, and fills in the color all by itself.   Neat huh?

When I'm feeling sad, tell me a silly joke and remind me that I'm not alone.
