If one strips away the trappings of sex-differentiating apparel, puts everyone in either pants or dresses, and makes hairstyle uniform (either short or long), the distinction between men and women may not be easy, especially in young people. Elizabethan drama capitalized on this by having male actors take all the female roles (yes, Juliet, Cleopatra, and Desdemona were all played by males). In our own era we are entertained by Dustin Hoffman playing Tootsie and conversely by Barbra Streisand playing Yentl. Further, the "ideal" shape has varied over time, particularly for females. For example, soft, well-cushioned women of the Rubens type were valued in Renaissance and Neoclassical times, perhaps because food was scarce and plumpness was difficult to achieve. Contemporary lifestyles that emphasize exercise and fitness have made male and female bodies look much more similar, especially among young adults. Many young women, as well as young men, pride themselves on their leanness and "muscle definition." Human males and females resemble one another more physically than they resemble other primates, such as chimps and gorillas. Apart from primary sexual characteristics (where there is a definite dichotomy), the statistical distribution of other physical characteristics of men and women have considerable overlap. There are tall women and short men, women who have more prominent facial and body hair and men who have little, women who are angular and muscular and men who are round and pyknic. The "average woman" differs from the "average man" in a statistically predictable way, but the differences in individuals cannot be predicted.
