Can't wear my rings on the bike, even if I wanted to. My hands swell. (Same when I'm running... or any sport, for that matter... or on a plane.) I always put my rings in the very same place in my apartment, and never ever take them off and put them, say, in my pockets. I would be really angry with myself if I lost them...

I don't wear earrings when I do sports, either. I can't bear the thought of what it would do to my earlobes if I was in a crash or something. Too much of a risk for very little aesthetic benefit, in my book of course. Note that I wear very little jewelry anyway.

So that leaves only my RoadID, which I wear in my neck (Fixx). It has a little flower etched on it...! And my sports watch, a Timex Triathlon that I definitely wouldn't call jewelry!
