How do our physical features (hair, skin, ears, nose, lips, eyes, etc.) influence our personal and cultural identities?

Our pysical features make us who we are. No two humans are alike. Although it's not always a great idea to "judge a book by its cover", we still do it anyways. People see us for our physical features and they influence their opinions of us. Some people may form opinions on a trait that is specific to a specific culture or group of people.
