I'm a 6'2" woman, can we trade heights please?
But seriously, you can't do anything to change your height/growth, that's determined by DNA. And just for clarification on the numbers you've seen online;
18-19: Maximum height usually achieved & 25: Fully formed cranial structure(complete physical brain development). But that's not to say you will not grow past 18-19, I've had some of my male friends jump another 3" from ages 19-21. Sorry for Imperial measurements, I'm not really sure what the Metric equivalents would be.
5'9 is rather tall, if you'd ask me. Then again, I'm only 5'1 so of course in my eyes you're tall. Even if you wouldn't grow anymore, you shouldn't worry about it though. You're good just the way you are.
