I'm 17 years old , going to be 18 next month . I'm about 5'8 and around 5'9 with shoes . My dad is around 5'5 and mom 5'0 . I have two brothers , one is 29 and same height as dad the other one is 14 and about 5'2 . Grandpa from dad's side was around 6'0 i think , he was half african. I started playing basketball so i want to grow taller and I'm worried I might not . Help me out a bit over here pls?
