How does this all work though? Doesn’t the body somehow have a certain growth limit specific to individuals that cannot be surpassed once it has been attained? It is understandable why people adhere to this opinion. Males, who are naturally supposed to be taller than females, don’t seem to be in control of their height. Some males are particularly tall while others are particularly short – and shorter than their female companions at that! The same is true for the opposite sex. Yet this is something people have grown to accept because they do not know that height increase can occur. To understand exactly why this is possible, we have to examine the substance produced by our body to promote growth.
