Probably because you've already filled one need, hunger, and you're feeling rather satisfied.  Also, it takes energy to digest.  When you're having sex and are hungry...you're ready for that matter at hand and you're putting all your energy into it.  At least that's my hypothesis.

Vomiting is supposed to expel dangerous stuffs from the stomach.\n\nSome evolutionary biologists believe that vomiting in response to odors is designed to prevent us from eating things that are bad for us.  For example, some carnivores can eat spoiled meat.  Humans can't.  The smell of spoiled meat makes us nauseated, and may even make us throw up so that we don't eat spoiled meat.  It may be an over-reaction.  We are supposed to feel sick to overcome any hunger pangs, but we go too far and throw up.

When you cry (this sounds corny but....) everything inside of you gets very worked up, you've been alive long enough to have eaten a lot of different things, chocolate, sugars, salt, any kind of food, your body knows what foods will stimulate, or calm your nerves, therefore causing you to want food.

this might be caused by an infection of the liver. you see it a lot in those campaigns to stop hunger in 3rd world countries. This is typically irreversible, but you should go to a doctor and get it diagnosed as soon as possible.

Because your stomach needs more blood when it is full of food, blood is shunted from the brain to the stomach.

I'm just going from memory, but I believe it's because the acids in your stomach are breaking down the food, causing gases and nastiness....which basically stinks....I'm sure someone will post a wiki....but that's the gist of it!

eat slower. burps are caused by excess air in the stomach that needs to be expelled. when people eat faster, they swallow more air than if they slow down a bit

When you hiccup, your diaphragm involuntarily contracts. (The diaphragm is a dome-shaped muscle that separates the chest cavity from the abdomen. It plays an extremely important role in breathing.)\n\nThis contraction of the diaphragm then causes an immediate and brief closure of the vocal cords, which produces the characteristic sound of a hiccup. What actually causes the hiccup is difficult to say - in most instances, there is no obvious cause.\n\nAttacks of the hiccups seem to be associated with a few different things: eating or drinking too fast; being nervous or excited; or having irritation in the stomach and/or throat.\n\nIn some extremely rare cases, the underlying cause of hiccups can be pleurisy (inflammation of the membrane lining of the lungs and chest cavity), pneumonia, certain disorders of the stomach or esophagus, pancreatitis, alcoholism, or hepatitis. Any one of these conditions can cause irritation of the diaphragm or of the phrenic nerves that supply the diaphragm - it's the irritation that causes the hiccups.\n\nStill, the cause of most attacks of the hiccups remains a mystery.

A person is supposed to eat every 4 hours(it takes so long for complete digestion of the food).\n\nWhen we have not eaten food for some time,the stomach is empty.the stomach wall will secrete acids(HCl) and enzymes for digestion of food wether food is present in stomach or not...this results in accumulation of acid and enzymes in the stomach which causes the "grumbling noise" in the stomach.\n\nThis signal's to the brain that the body needs food...thereby causing hunger pangs.

Yes it does. Greesy/fatty food, and anything you have trouble processing like milk and dairy cause gas (flatulence). It's caused by the billions of bacteria in your intestine that process the food and let out a gas as a byproduct. Once it accumulates the sound is made by the vibration of the anus, similar to a tuba player buzzing their lips in a mouthpiece. Nice image eh?

Your stomach makes noises because your it is contracting and trying to digest but all that is in there is your gastric juices, it's kind of like squsihing a water ballon that is only a little bit full

Feeling hungry has nothing to do with food hitting or not hitting the bottom of your stomach.  Their stomachs do growl and they do feel hungry.

hiccups are an involantary muscle spasm of the diaphram.  usually occurs when you are dehydrated and are eating or immediatly following a meal. your body needs fluid in your esophugas to move food to your stomach through peristalsis
