Physical attractiveness refers to a person's physical traits which are perceived to be aesthetically pleasing or beautiful. The term often implies sexual attractiveness or desirability, but can also be distinct from the two; for example, humans may regard the young as attractive for various reasons, but without sexual attraction. There are many factors which influence one person's attraction to another, with physical aspects being one of them. In many cases, humans attribute positive characteristics, such as intelligence and honesty, to physically attractive people without consciously realizing it.
Men, on average, tend to be attracted by women who are shorter than they are, have a youthful appearance and exhibit features such as a symmetrical face,full breasts, full lips, and a low waist-hip ratio.Women, on average, tend to be more attracted to men who are taller than they are, display a high-degree of facial symmetry, masculine facial dimorphism, and who have broad shoulders, a relatively narrow waist and V-shaped torso.
Generally, physical attraction can be studied from a number of perspectives, including universal perceptions common to all human cultures, cultural and social aspects, and individual subjective preferences. Additionally, the perception of attractiveness can have a significant effect on how people are judged in terms of employment or social opportunities, friendship, sexual behavior, and marriage.
Some physical features are attractive in both men and women, particularly bodily and facial symmetry, although one contrary report suggests that "absolute flawlessness" with perfect symmetry can be "disturbing". Symmetry may be evolutionarily beneficial as a sign of health because asymmetry "signals past illness or injury". One study suggested people were able to "gauge beauty at a subliminal level" by seeing only a glimpse of a picture for one-hundredth of a second. Other important factors include youthfulness, skin clarity and smoothness of skin; and "vivid color" in the eyes and hair.But there are numerous differences based on gender.
