Dear Charlie:
The answer is nope, you can't! You have two tubes running from the top of your throat: a windpipe
that takes air to your lungs and an esophagus which takes food to your stomach.
So--what keeps food from going down the wrong tube? Thankfully, your body comes with a trap
door which slams down on the windpipe when you eat so that food can't go down your windpipe and
head straight for your lungs.
However, it IS possible for you, to swallow some air. And, if you do, you may find yourself
sending that air right back up in a big belch.
Signed,
Wendell
