Well, I'm confused again, but in a good way. I thought I was 5' 6" tall (after losing nearly an inch in height in a serious accident), but I measured myself recently and got my height as 5' 7", which I was mightily annoyed about.
But today, I had a check-up at the doctors, and the nurse measured my height, and she said I was 5' 6".
So that's a relief, I'm back to the height I prefer, whew!
