  Height is just one of the thousands of features your genes decide. In fact, becau you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall, too, but if you have questions about how tall you’re going to be, ask your doctor if he or she can help you find it out.But genes don’t decide everything.

Getting plenty of sleep and enough exerci will help you grow to the expected height.No doubt you’re wondering how fast you should grow. It depends. There’s no perfect or right answer.
