The most obvious difference at first glance is that in Azeroth, all men are blocky and all women are curvy. Aside from various facial traits, hair and skin color, humans don't vary from this standard mold. Even in advanced age, Azerothian women's breasts do not sag, nor do men's muscles lose their beefy bulkiness. Some Earthlings have disparagingly compared Azerothian men to gorillas for their tree-trunk arms and their "smashed-with-a-shovel" faces, but others point out that Azerothian humans have been hardened through great suffering. Wars with orcs, demons and undead have reduced their population from millions to mere hundreds of thousands, and so the weak humans of Azeroth have possibly been weeded out. So, while many Earthling humans may enjoy the comforts of working at a desk all day, then coming home to play at a desk too (i.e. via computer game), Azerothians, even old ones, have to keep themselves fit to fight off the various enemies encroaching on their lands, such as murloc flesheaters and forsaken undead. While this may explain the over-muscled arms of Azerothian males, it leaves the question of youthfully curved elderly women quite unanswered.
