Let's discuss why this doesn't work. When we are infants, our bones are still mostly cartilage. As we grow gradually, this cartilage hardens and melds into hard adult bones, which is why we have considerably less bones than we do when we're babies. While we hit puberty, cartilage growth plates located on the ends of our longer bones causes those bones to lengthen slowly. Exercising regularly during this time can enhance your height, but once your bones stop growing, no amount of stretching will make them grow again.
In fact, the only way to lengthen your bones once you reach adulthood is to have surgery performed. However, this is extremely difficult and has several risks involved. You must be thoroughly psychologically evaluated before undergoing the test. It's also difficult to find a doctor who has the experience necessarily to perform this.
During the surgery, your legs are broken and metal plates secured to hold the bone in place with a gap between them. Over the course of several months, your bones gradually grow together to fill the gap. However, as you can imagine, the recovery time for such a surgery takes a very long time, and you may need physical therapy afterward. The risks involve the bones healing wrong. They can heal in a way that results in the bone being warped for life. Other risks involve paralysis, nerve damage, and even death.
If you're considering how to grow taller, there are better alternatives than surgery. For example, dressing to look taller is a safer and cheaper alternative. By wearing solid, dark colors, pinstripes, and high heeled shoes, you can make yourself look considerably taller. In contrast, wearing dark pants with a white shirt or clothing with plaid or polka dots can make you look shorter, as it draws attention to your middle and makes your limbs look shorter.
