27 year-old, 7 year one tin/day dipper. No one knows (except old college buddies). Somehow I've even been able to keep it hidden from the GF, family, and most friends. I think that's going to make it tougher to quit. Maybe that's one thing that makes us different from smokers, the scent isn't seeping from our skin. It's really the one thing I don't like about myself.
