I know how the wooden beams in my office smell. My mind can summon the smell of the handrails in the train station, disturbingly. The smell of my clothes, and crotch, before and after workout, it's right there. It takes me a while to accept clothes I got from other people as my own. Using strangers' detergent alienates me from my own clothes. I don't like to touch things I know other people touch. (It's a weak effect, and doesn't bother me.) Is this related to smell? Do I not like getting other people's smell on my hands? Or is it just hygiene training? Hard to tell. If you were to count, I'd be smelling my hands a lot less when riding a bicycle not my own. Judging by that study. It's interesting how the authors speculate about the link between self-smelling and consciousness. I am who I smell.
