A human is usually between 140cm and 180cm tall, though this greatly depends on race, gender and living conditions. Historically, human body height has increased, especially in the twentieth century. Humans can have a black, brown, blonde or ginger hair color, though they can dye it in any color. Their eyes are usually brown, blue, grey or green.
