When you swallow something that is too hot or cold, some people feel it down the front of their bodies and others feel it down their backs. Why is this? I'm not an anatomist, but when something is swallowed it goes down the esophagus and you can feel it go down. The feelings of front or back are very subjective and may depend upon what you've just been doing or where your attention is at that moment. Also, note that the localization of sensations inside the body is not that well defined. With your hands for example, as you grow up touching things, you figure out where the sensations are. But with internal organs, there is none of this training. For example, heart attacks are often felt as indigestion or other pains in the torso. Appendicitis is sometimes felt higher up, or in other places where the appendix isn't. Similarly, the sensations from swallowing can vary from person to person. But no particular way should be thought of as "correct", it's just the way it turned out for that person. Mike Conrad
