hi  growth is possible at 19 but not very drastic. 165 cms is normal and your height is also dependent on genetic factor also don't need to worry, but if you have disproportionate height consult a physician

hello..there is a certain age up to which our bone length increases..after that there will be no increase in height...your maximum growth spurt would have already occurred..generally in puberty everyone grows up to adult height..there may be hardly any height increase after that won't be there.. so until early 20's there are chances of increase in height
