Did I do something to cause growth spurts (3 inch total) @ 36 & 41? NO other physical changes. Height was the same for yrs; reached adult ht early 20s

Growth. 45 F Pa notes growth spurts at 36 and 41 with 3 inch total. ANS: this is impossible as height fixed when bones stop growing much younger. So issue is how height wax measured. Suspect measurement ertor such as wearing shoes or heels?
