by Jordan Gaines Lewis in Gaines, on Brains

Prosopagnosia: Why Some are Blind to Faces

by Jordan Gaines Lewis in Gaines, on Brains

He eyed me strangely and walked a couple steps closer before returning the greeting. "Oh, didn't recognize you in the coat. You were wearing green earlier. Have a good night, Jordan."
