" Verbal facility with smells and flavors doesn’t come naturally. As babies, we learn to talk by naming what we see. “Baby points to a lamp, mother says, ‘Yes, a lamp,’” says Johan Lundström, a biological psychologist with the Monell Chemical Senses Center in Philadelphia. “Baby smells an odor, mother says nothing.” All our lives, we communicate through visuals. No one, with a possible exception made for Sue Langstaff, would say, “Go left at the smell of simmering hotdogs. "
