I m 5 foot 4 and I m 20 now turning 21, what can I do to increase my height? I actually come from a tall family both my dad and gramps are 6 feet and taller. I think I m short cause I drank soda, didn t sleep right, didn t excersize, and slept on a bed that was horrible for my back, but hey is there a chance to fix my mistakes and make up for my hieght? do pills help?
