Something to note: the effect gravity has on living beings is not soley influenced by the worlds mass. The gravitational pull of the sun it orbits, as well as the constant motion of the world spinning, affects everything in subtle yet great ways. Some scientists believe the reason you only grow to a certain length or won't become flat is because the stars gravity constantly conflicts with the planets, constantly adding pressure to both points, assuring you will not become a wobling piece of meat or a little round ball weighing near 600 kilo's because of the squeezed mass.

Then there's the whole wind gale but that is not something i know much about so i will just say that it probably does something :3
