people (the man) grow at a specified rate , and between 10 years of age and 20 years of age this man grew over 1 foot (so that his belt is 1 foot higher). trees , in certain circumstances are completely full grown at 10 years of age so that the nail will remain at that height for the entire life of that tree
Reply:Humans grow in all parts of their bodies, including their legs. Trees grow from the top, not at the base.
