wow your growth is not going as fast as it should be by 20 you should be about 5'3 am guessing do alot of kick boxing and cycling its been proven once you continoiuly work on these two it triggers the growth hormone in the brain to make you taller try it and see if it works and also deep sleep activates growths hormome and sleep without a pillow as this lengths the spine when you sleep with a pillow it pushes the spine up which is what you dont want
