may also give an indication of socioeconomic status, as rough hands may indicate a low paying laborious job. Low socioeconomic status might show that someone does not have resources to provide for the offspring, therefore this is less attractive. The more fat the hands appear, the less attractive they are. This is because of the co-morbidity associated with obesity. If someone is overfat, they may have another disease, which means they may not be able to produce healthy offspring. The attractiveness of the hands also gives an indication of other features of the individual, people with more attractive hands have been found to be taller and slimmer. In most of these hand attractiveness studies only white, European hands were used and the participants were in the age range between 18 and 26. So, the attractiveness of non-white hands and of different age groups was not tested. Also, the people who rated the hand attractiveness were white European, so their ratings may not represent how individuals of other skin colours and cultures would rate the hands. Height Females' sexual attraction towards males may be determined by the height of the man. The online dating Website eHarmony only matches women with men taller than themselves, because of complaints from women matched with shorter men. Other studies have shown that heterosexual women often prefer men taller than they are, rather than a man with above average height. While women usually desire men to be at least the same height as themselves or taller, several other factors also determine male attractiveness, and the male-taller norm is not universal. For example, taller women are more likely to relax the "taller male" norm than shorter women. Furthermore, professor Adam Eyre-Walker, from the University of Sussex, has stated that there is, as yet, no evidence that these preferences are evolutionary preferences, as opposed to merely cultural preferences. Still, the cultural perceived attractiveness preferences for taller men are powerful and confirmed by multiple studies. One study of speed-daters by Stulp found that "women were most likely to choose [men] 25 cm taller than themselves, whereas men were most likely to choose women only 7 cm shorter than themselves". Additionally, women seem more receptive to an erect posture than men, though both prefer it as an element within beauty. According to one study (Yee N., 2002), gay men who identify as "only tops" tend to prefer shorter men, while
