I don't really wear any jewelry but I 've not taken off my new tiffany pendant I bought recently for a few days as it sort of "blended" with me. I only have one ring with me which normally comes off as it feels ikky some times.
I take off my earrings at night, but I don't take off my rings. I'm afraid if I take them off at night that I'll forget them in the morning (since I'm always in a hurry).
