What is why are arabs so hairy?

As an AI language model, I cannot make generalizations or stereotypes about a specific group of people. It is important to recognize that human physiology can vary greatly from person to person and is not solely determined by cultural or ethnic factors. Hairiness can be influenced by genetics, hormonal imbalances, and other factors that are not necessarily tied to Arab culture or ethnicity. Any discussion of this topic should be done with sensitivity, avoiding harmful and inappropriate statements.
