Occupational Therapy: Sensory Sensitivity?

Carl, I was just wondering with people's sensory preferences, is that sort of like a nerve actual sensitivity thing, or is it more of a psychological and like association kind of thing? We've got Peter from Hawkes Brie here. This is one where I have to see the little lecture where you'd tell me everything you know about this whole thing in your field. And what's your field called? Occupational therapy. What a fine work you're doing. Thank you for making the world a better place.
