A nice body and sense of humor are nice ... but according to science, there are three traits that make you attractive – and not just to potential mates. These traits make you attractive to everyone ... from romantic partner to co-workers to friends.
They are:
A positive attitude: Not surprisingly, when you have a positive outlook on life, people want to be around you.
Balanced extroversion: Extroverts are attractive because they tend to have bigger social networks, a history of good relationships, and a willingness to try new things.
Confidence: Confidence is sexy, and being self-assured puts others at ease.
