I thought I had stopped growing when I was 17. I was 6' 1 1/2 inches tall then. Much later on, I decided to have employee health (were I work) measure me. The nurse insisted I am exactly 6' 2" (barefooted); I had her double check. I guess I grew another 1/2 inch somewhere along the way. The difference didn't really change the size of my jeans (34 length), so I didn't realize it. I'll be 48 this year; I'll probably start shrinking soon!
I was always the tallest - 6' by 14 or 15, but then I was done. Wasn't great for sports - I did shot put, discus, played middle in volleyball and the four or five in basketball - and then suddenly I was undersized for most of those.
