My ring size went from 6.5 some 35 years ago, to 7, to 8, and now back to 6.5 at age 56. I'm sad because my rings are too big and I don't have a trustworthy enough bench to size one, and the other can't be sized again and would need a reset. My "good" set lives in the safe, never to be sized because it's too special to be touched, lol, and is size 7. So in life you never know. I have arthritic hands but still my size went down with age.
