Just an interesting article on body language.  Some good advice for the workplace.

1. Stand tall, even if you’re the shortest person in the room. Keeping your shoulders pushed back will lend you an air of confidence.
2. Spread your weight evenly on both feet instead of leaning on one. You don’t need to stand at perfect attention, just keep your feet apart so you balance well.
3. Take your hands out of your pockets, or you may be seen like you’ve got something to hide. Hold them loosely by your side.

Number 1 will even make you seem skinnier.
