Ooo, that body's like music to my ear!

"Now, I don't speak Spanish, Japanese or French

But the way that body's talkin' definitely makes sense"

I know it's not a new song but I love this one right here "Body Language"-Jesse McCartney

And thats why... Body language says a lot! Stand up straight. Let others know that you respect yourself, and they will follow your lead. Plus, it has the visual effect of smoothing out any bulges that aren't particularly flattering. Posture is important and can make you look more attractive. Standing or sitting slumped burns fewer calories then sitting or standing up straight.

Now look at the difference:

 Not standing straight                                                            
                                        Standing straight
