Forget about opposites attracting. We like people who look like us, because they tend to have personalities similar to our own。
And, a new study suggests, the longer we are with someone, the more similarities in appearance grow。
Researcher sat Wake Forest University School of Medicine in Winston-Salem, North Carolina, found that workers who enjoyed more work flexibility were also less likely to say health problems affected their performance at work。
The test participants rated men and woman who were actual couples as looking alike and having similar personalities. Also,the longer the couples had been together, the greater the perceived similarities。
The researchers speculate that the sharing of experiences might affect how couples look。
The idea that there is a connection between appearance and personality might seem odd at first, but there could be biological reasons for alink, said study member Tony Little from the University of Liverpool in England。
"Testosteroneis linked to masculine face shapes and it also affects behavior,"Little said. "Also, the face displays our emotions and over time emotional expressions may become written in the face."
