I am almost 22 years old...wanna increase my height.....is it possible...??? and if yes then pls tell me the medicines and what i have to do..

Nothing: Unfortunately at 22 years of age you have likely reached adult height. Ultimately genetic plays the most powerful role in determining your final adult height. Of course good nutrition, lots of sleep, and a nurturing environment as a child can effect total height as well, but in your case there is not much chance you will get any taller.

Platform shoes: At a listed age of 22, there is little hope you can "grow" taller.The growth centers that determine linear growth close after adolescence, at 16-17 in most females and 18 in most males.After closure, you can not grow taller. A single x-ray of your wrist and hand can tell if your growth plates remain open, if not you are done.
