Odd, I was married for almost twenty years during which I think I took off my ring twice (maybe not even that much—if I recall correctly, I persuaded the surgical staff to tape my ring rather than have me remove it when I had surgery). Never had to resize it and it fit fine the whole time. I don’t know what lifestyle leads to a finger changing size dramatically during the lifespan of a smart ring.

Are you pretending that you are unaware that this can happen, or are you showing contempt for people who gain or lose weight? I don't find either useful.

Ever heard of arthritis?
