美女比較會偷吃？德州大學奧斯汀分校的研究人員發現，重要雌激素「雌二醇（estradiol）」分泌旺盛的女性，不但魅力十足，同時也往往會一個接一個男人換；但這不代表她們會追求刺激的「一夜情」，反倒比較像「騎驢找馬」。
這項刊登在英國皇家學會刊物「生物學通訊」的研究結果顯示，雌二醇高的女性，不但自我評價較高，旁人也會覺得她們更有魅力；另外，這些雌二醇高的女性更可能調情、親吻、或是和其他男人發生認真的劈腿戀情，也會更願意和其他男人約會。
研究負責人杜蘭特教授說，男人很難同時兼具財力跟良好基因，因此長期穩定的「飯票」、或基因良好的短期性伴侶，女人往往只能擇一；但雌二醇高的女性對男性的標準更高、也更不願從一而終，如果身邊的男性不是太令人滿意，一旦條件更好的男性出現，她很可能就會開始跟他培養關係，最後甚至轉而求去。
她說這種模式比較像「投機性的連續單配偶制」：她們不是在性上面隨便的人，只是會用自己的好條件找到更好的男人。
杜蘭特等人的研究方法是找來五十二位十七到三十歲之間的女性，先為她們測量兩次雌二醇濃度，然後要求她們為自己的魅力評分，最後再由不知情的兩男七女為每個實驗對象評分。

Oestradiol level and opportunistic mating in women
ABSTRACT
The ovarian steroid hormone oestradiol plays a crucial role in female fertility, sexual motivation and behaviour. We investigated the relationship between oestradiol and the likelihood that women would engage in opportunistic mating. Two salivary samples were taken from normally cycling women within the peri-ovulatory and luteal phase of the menstrual cycle. At both testing sessions, participants also completed self-perceived desirability scales and provided subjective reports of sexual and social motivations, and satisfaction with their primary relationship partner. Oestradiol level was positively associated with a woman's self- and other-perceived physical attractiveness and with inclinations to mate outside her current relationship. Oestradiol was marginally negatively associated with a woman's satisfaction with her primary partner and relationship commitment. Results provide support for the relationship between physical beauty and fertility and suggest that physiological mechanisms play a major role in guiding a woman's mating strategies.

應該說與 estradiol 濃度高低與自覺和他覺 sexual/physical attraction相關, 而非 "estradiol 分泌過高".....

A Boy with a Mission
bump the thread up.
In 1945, a 12-year-old boy saw something in a shop window that set his heart racing. But the price—five dollars—was far beyond Reuben Earle's means. Five dollars would buy almost a week's groceries for his family.
Reuben couldn't ask his father for the money. Everything Mark Earle made through fishing in Bay Roberts, Newfoundland, Canada. Reuben's mother, Dora, stretched like elastic to feed and clothe their five children.
Nevertheless, he opened the shop's weathered door and went inside. Standing proud and straight in his flour-sack shirt and washed-out trousers, he told the shopkeeper what he wanted, adding, “But I don't have the money right now. Can you please hold it for me for some time?”
“I'll try," the shopkeeper smiled. “Folks around here don't usually have that kind of money to spend on things. It should keep for a while.”
