Agree. When I turned up at 5'3 after many months of them recording that I was 5'4 I wanted to know why. My doctor admitted that on visits where they don't take my height, they just use the last measurement so my information is wrong on my records for years at a time. I don't think they take these things carefully.

You do lose height as you age due to compression of your vertebrae. It happens to everyone.

I also feel like if you gain weight or are fat you will get a wrong measurement. My backside is sort of far from the measurement stick and I feel like bending back sot of takes off a 1/2 inch or so.
