Your First Date: Make Sure Your Genes Fit

Getting ready for a first date involves preparations to look and feel good. It might involve a new ‘do,’ a clean shave, or fresh new outfit with a great pair of jeans that fit perfectly. But great-fitting jeans are not the only thing that people are making sure fit before their first date. People can now check that their genes fit. Yep, genes -- as in our DNA -- before going on a first date. 

Love Is In the Air

Our body smell is an important determining factor of whether someone else finds us attractive or not. In fact, I can’t think of a single person I know who is really attracted to someone they think smells bad. If anything, people remark at how good the person smells. In fact, smell is so important that a huge industry making perfumes and colognes thrives off our desire to smell good to one another. Smell is so important that women rank it higher than appearance when asked what they consider to be the single most important variable in mate choice!

Late to the Game, Happier in Relationships

According to a recent study published in Psychological Science,1 teenagers who wait longer to have sex experience different kinds of romantic relationships later in life compared to teens that start having sex earlier. This 15-year longitudinal study (beginning in 1994 and concluding in 2009) tracked teenagers’ sexual activity and long-term relationships into their late 20s/early 30s. Those teens that had sex before age 15 (23%) were considered “early” sexual bloomers. Most teens (60%) had sex for the first time between the ages of 15 and 19, which scientists consider normal for American teenagers (thus, “on time”), and 16% of teens reported having sex for the first time after age 19, and were labeled “late” sexual bloomers (8% of the sample did not report having sex at all in their lives).

Hard-Wired for Care? A Genetic Basis for Providing Care to a Partner in Need

It’s not too profound to suggest that people are biological creatures—without genes, bodies, and brains, no part of our social lives would be possible. But how our biology relates to our minds and behavior has been a black box for centuries. Scientists simply didn’t have the tools or level of biological knowledge necessary to connect what happens in our bodies to how we experience the world. In the last 30 years, however, advances in genetics, physiological recording, and brain imaging have made it possible to begin to unpack some of the links between biology and psychology.
