Some girls are naturally that thin. I was until I was 45. I got some very rude questions about it. It was awful. On the “up” side I could eat anything and as much as I wanted. I am now trying to adjust to that no longer being true. lol
Me, too. I was very slender till I hit about 51, then I started packing on the pounds. I am 5’6’ and always weighed around 105 to 110. Now I weigh around 125 to 130.
