It is a question which no one has answered for centuries.
But now, scientists have discovered a new answer.
The answer is simple.
People choose to look beautiful.
And this can be seen in the images we take and the way we think about beauty.
A new study has shown that beautiful people have higher brain activity than those with less attractive characteristics, according to researchers from the University of Bath.
The findings, published in the journal Brain Research, found that those with high levels of the dopamine receptor protein, a brain chemical involved in reward, were more active in the visual cortex of their brains.
Dopamine, also known as the “feel good” hormone, is associated with feeling pleasure, reward and pleasure, says Dr Rachael Karpinski, who led the study from the School of Biological and Chemical Sciences.
“It’s not just about what’s good or bad, but also about what we like to do,” Dr Karpinsky says.
“In our brain, dopamine and other brain chemicals are involved in the way that we respond to pleasurable or painful stimuli.”
“Our brain is wired to want to look good.
And in order to do that we need dopamine.”
The researchers found that a person with high dopamine levels had greater activity in the region of the brain known as ventral striatum, which is associated mainly with reward and motivation.
“This finding provides evidence for a link between reward and reward-seeking behavior,” Dr Sari Elinav, from the Department of Psychological Sciences at the University at Buffalo, New York, said.
“There are a lot of people out there who don’t have high dopamine and don’t look good, and they’re not doing that.”
So we wanted to find out why.
“Dr Elinav says the findings provide a new explanation for why some people look so good.”
People with low dopamine are not rewarding themselves for the good things they do, they’re rewarded by their negative thoughts and emotions,” she says.
Dr Elavas work in the laboratory of Dr Kupinski and her colleagues was funded by the Australian Research Council, the Australian National Health and Medical Research Council and the European Union.
