Science of Sex: Whats Your Type?

One of the easiest ways to sum up a potential mates shortcomings is with the simple phrase, Hes just not my type. But why do we have types? Most people can write down a list of must-haves and must-not-haveseverything from job status and music taste to eye color and shoe preference (mandals are a surefire deal breaker). But the reasons why people have types and the things that drive their finicky tastes are less clear.Rules of Attraction
Its not hard for scientists to determine the traits that make people attractive: a good waist-to-hip ratio;symmetrical features; for men, a masculine jaw and a deep voice; for women, a high voice. All these characteristics relate to hormone levels and overall genetic fitness. Were attracted to people with whom well have a good chance of having healthy offspring, even if were only looking for a fun night or two.Scent also plays a large role in what we consider chemistry and relates to how our own immune system matches up with a potential suitors.But rarely do we describe our type as someone whos symmetrical or who has kick-butt immune defenses. Instead, we want someone whos athletic or artsy, or someone who has oodles of ambition and the 401k to prove it.Birds of a Feather?
Our perfect type may have less to do with biological attraction and more to do with our own personality, style, and interests. Studies have shown that people tend to fall in love with those from their same socioeconomic background, similar levels of intelligence, and consistent values and principles. Theres even a termhomophily, or love of the samethat describes the tendency for similar people to attract each other.In both romantic and platonic relationships, homophily happens. Researchers atMITs Media Laboratory looked at homophily in online dating and found that users sought people that were like them most of the time, just as it happens in the offline world. Users were most l! ikely to seek similarities in preferences for marital history and desire for children, but also things like physical build, attractiveness, and smoking habits.

Get Married, Live Longer?

Written by Jessica Cruel for YourTango.com New research shows that getting married could lengthen your life for up to 17 years .A study published in The American Journal Of Epidemiology reveals that single men have a 32 percent higher chance of death than married men across a lifetime. That means they could die eight to 17 years before the average married man of loneliness? Single women fare a bit better: They have a 23 percent (or about seven to 15 years) lower life expectancy compared to their married peers. This data is based on 90 studies of around 500 million people compiled over the last 60 years by researchers at the University of Louisville: No small feat. Younger singles face greater chances of early death. The risk of death for 30 to 39-year-old singles was 128 percent higher than for married people of the same age. On the other hand, 70-year-old singles only had a 16 percent higher risk of death. Perhaps its because theyve survived a single youth and emerged unscathed. These...

Red Wine Reduced Breast Cancer Cells

Italian researchers from the University of Calabria say they demonstrated how a key ingredient in red wine inhibits the proliferation of human breast cancer cells . Resveratrol is the ingredient they say might be useful in the treatment of breast cancer, in addition to primary therapies. In their experiment resveratrol was applied to different cells and compared to cells that received no treatment. The cells receiving resveratrol showed a decrease in growth. A large reduction in estrogen receptor levels was believed to be related to the inhibition of the breast cancer cells. Their research study was published in the Journal of the Federation of American Societies forExperimental Biology. These findings are exciting, but in no way does it mean that should people go out and start using red wine or resveratrol supplements as a treatment for breast cancer, said Gerald Weissmann, M.D., Editor-in-Chief. (Source: ScienceDaily.com ) He said the research is more about the potential of resverat...
