The answer is in their body language.
A new study says the body provides more reliable evidence of a person’s emotional state than a smile or grimace.
Medical journal Science published research that used images of tennis players at the moment they won or lost. The Hebrew University of Jerusalem showed the pictures to study participants, confining the image to the face or body for different participants.
Those who saw only the body correctly guessed the player’s emotional state; the face-only group was more likely to be wrong. After merging the faces of winners onto the bodies of losers, study participants still correctly stated whether the tennis player was happy or sad — indicating the importance of body language.
“You can’t tell from the face alone if something good’s going on or bad going on...,” said study co-author and psycholo-gist, Hillel Avieze. “The body maintains a clear signal of positive and negative. People use information from the body and then they read it into the face.”

Some people are hard-wired to binge drink because they have higher levels of a ‘happy’ brain chemical triggered by alcohol. The discovery of the RASGRF-2 gene could be a solution for problem drinkers. King’s College London researchers made the finding after examining the brains of 600 teens and their dopamine responses. Those with higher dopamine levels were more likely to binge drink in early adulthood.

Pregnant women have been urged to ensure they are getting enough vitamin D to prevent medical problems in their kids. A new study said the lack of ultra-violet light in Ireland between October and March means babies born in spring are up to 5% more likely in adulthood to suffer from stunted growth or develop multiple sclerosis than those born in other seasons.
Experts said the rate is lowest among children born in October. The research team say any pregnant woman in northern Europe could be affected.

Eating healthily not only helps prevent an increased risk of heart problems, it also significantly reduces the risk of problems among people who have suffered heart attacks or stroke. An international five-year study made the finding after examining 32,000 people in 40 countries. The major research examined participants’ lifestyle choices, smoking and alcohol habits, and weekly level of exercise.
It found that eating healthily led to a 14% cut in heart-attack risk and a 19% reduction in stroke, even among people who have suffered from the conditions.
