curious... i, too, finally realized i was standing in a cafeteria and didn't smell a thing. Once I put down my barriers that i keep up all the time and really thought about it, i could then smell the food - or at least i think so. i suppose i could have just been remembering what those foods smell like.
so now days i test myself every once and a while - i see food; can i smell it?
some smells are triggers for me - butter and hamburger in particular.
