Symmetry equals sex Starting at conception, the human body develops by neatly splitting cells.If every division were to go perfectly, the result would be a baby whose left and right sides are mirror images. Genetic mutations and environmental pressures skew symmetry, and the results have lifelong implications.To figure out how we pick mates, scientists have measured every shape and angle of the human face, studied the symmetry of dancers, crafted formulas from the measurements of Playboy models, and had both men and women rank attractiveness based on smelling armpit sweat.After all this and more, the rules of attraction for the human species are still not clearly understood.In fact, romantic relationships remain among the most psychologically challenging engagements we face.Whether or not individuals are in relationships, older adults are living longer—and longevity is better in a relationship.
No pun intended, but for many, these may sound like very strange bedfellows.UNICEF reported in March, as paraphrased by the Associated Press, that early marriage in Yemen has become "alarmingly widespread." In a survey conducted in September in six provinces, 72 percent of female respondents said they got married before 18 — compared with around 50 percent in surveys before the war — and about 44 percent said they were wedded before they turned 15, the organization said."Parents marry off their daughters to be relieved of the cost of their care or because they believe a husband's family can offer better protection," UNICEF said."Families also seek dowry payments to cope with conflict-related hardship." A father ran out of cash while buying qat — leaves habitually chewed as a stimulant in Yemen — so he gave his daughter to the dealer in marriage.Another man married off his daughter three times in two years for repeated dowries, all before she turned 18.One gay survivor of the camps, LD Classen von Neudegg, has written about his experiences.
