I'll mention a few reasons why dancing enhances one's social life and how it generally improve one's quality of life.
1) Dancing helps you meet different people and make new friends. When you meet someone at a ballroom & latin class, you already have something in common. You want to learn how to dance. You'll therefore have something to talk about as you dance. Dancing with a partner means that you can have a more developed conversation later on which can involve more people. From that point on, anything is possible. People who dance together have been known to hang out with each other outside of their class, going out for movies, lunch or even more dancing.
2) Dancing increases your self esteem and confidence. The dance community is an open and friendly community. From the moment you walk in the door, you feel welcomed, whether it is at a salsa club or at your dance class. You find yourself in a place that is fun, open and energizing. Learning how to move well on the dance floor and seeing yourself constantly improving is major boost in confidence. Being able to walk up to a guy and asking them to dance shows the amount of confidence that can be gained by us ladies while guys learn to be able to ask any girl to dance.
3) Dance offers an activity for people who may not consider themselves as sporty. The benefit of dance is not only that of increased exercise, but the participation in an art-form, which is rooted in technique, which gives an opportunity for a creative outlet.
4) Dance can offer insight into other cultures, either through the dance style itself or by meeting new people. Paso or Salsa anyone?
5)You may meet your special person. I've seen so many people who have met through dance and end up dating. Imagine finding someone who loves dancing as much as you do. No awkward first dates. And the person is likely to have great posture too (maybe? no?) Imagine dancing the Argentine tango with your other half though. Pretty hot!
If you're a bit skeptical, check out your nearest salsa club, go to a swing party or any dance social. You will see what I'm talking about. Dancing is fun. Embrace it. And dance some more. Life is too short not too :) And obviously, there will be people who are just not interested but they're missing out in my opinion.
