Will my 62 yr old cousin grow anymore? She is 5'7 or 1.70cm

I am a bit taller than her I am 5’9" or 184 cm but we look the same height in mirror because it’s very small difference. She used to tease me when I was 42 and 5'5. She used to proudly say her height to me. But now my sudden growth spurts made me tall. Nowadays she calls me her big brother
