A comment in the Rachel Ray thread reminded me of a continuing difference between MrsF and I:
She can't bear the thought of food when she's already full.
After a big meal, if something novel passes our table, my eyes will go wide, or the aroma turns my head, I'll say, "That smells/looks great!" to which I get a response of, "Ugh! How can you even think about more food?"
Same for watching FoodTV, passing by bakeries, pushcarts, etc.
I'm not expecting to eat more (usually), I'm just appreciative of the sensory bonanzas around me.
On the flip side, does watching cooking TV shows make you hungrier? Me not so much, it's mostly an intellectual process, as Emeril says, there's no Smell-o-vision.
