It was from a book recommended to me by a family member that I learnt that; I recall that I too breathed with my chest. Perhaps it is the instinctual or cultural tendency to "puff out one's chest" that leads people to get into the habit? Upon learning this about five years ago, I've made a deliberate effort to breath with my diaphragm more, so it's certainly possible to learn the 'correct' habit!
