"Giantism" and read about it. A defect in your brain keeps you always growing, when you hit puberty at 12-13 years of age, it never ends, the only way people who have had this problem have fixed it, is to have a tumor in their brain removed. The tumor pressures the pituitary gland and makes it malfunction always giving you hormones to grow.
