I've been doing a lot of perfume evaluations lately and I noticed something kind of...interesting. I spray perfume on both arms but can smell the scent much better from my left. I started thinking about how when we tilt our heads we may favor one direction over another. Or when we clasp our hands we usually clasp them the same way each time. Now I'm wondering if being able to smell perfume more on one arm than the other is just a personal quirk or if there is some left vs right science behind it.
