How could a 20-year-old grow taller?

Platform shoes: If you entered puberty the same time as your friends ; your bone maturity is 18 yo or older there is little you can do to increase your height.A single x-ray of your left hand can be assessed for bone maturity.If bony maturity is more like 15 you might grow an additional couple of inches.Medicines won't help if the growth centers are closed/finished.
