Consider the case of Melissa, a 32-year-old news writer in Washington, who, after 10 mind-numbing years on the job, had a serious bout of malaise, felt that life had passed her by, decided to quit the damn job and cash out her savings, and went solo vagabonding in the wilds of South America.

One balmy night on the deck of a boat cruising off the coast of Ecuador, she found herself enveloped in the arms of the boat's swashbuckling captain. They kissed -- deeply, passionately. She experienced a sense of absolute liberation, a thrill of letting go. She felt flooded with life-giving energy. Her world, to put it simply, was rocked.

Melissa's cathartic kiss definitely made her feel better, and it might even have been good for her health.

Adrianne Blue's 1997 book "On Kissing" outlines the physiology behind the fireworks. Kissing is a highly orchestrated maneuver. You lean in, tilt your head to avoid a nose collision, and the muscles in your shoulder, neck and back are called into play as the brain's motor center gears itself to the delicate task of steering the lips and tongue. Your lips are loaded with nerve endings, and as your mouth meets your partner's, impulses fire through your neural network. Your brain tells your lungs to work harder, your heart to beat faster, your salivary glands to pump moisture into your mouth. Your jaw, the one movable bone in the human skull, hinges open as you extend your tongue.

Then, as tongues touch, neural signals go zipping along your spine, to your pancreas, your adrenal glands and pelvic nerve. Your arteries and veins dilate -- your heart rate shoots up, maybe doubles. Your lips swell, and you get that pleasant tingling sensation in your private parts. The blood rushing to your skin's surface makes you feel fevered, your face flushed. You may begin to sweat.

This ritual is what anthropologists call pre-copulatory activity, what sex manuals call foreplay and what Marvin Gaye calls getting it on. And getting it on is good for your health. In his book "Superimmunity," Dr. Paul Pearsall says that sex in the context of a loving relationship boosts chemicals in your body that protect against disease. Doctors believe that physical touch itself boosts levels of the hormone oxytocin. Among other things, oxytocin boosts feelings of affection and promotes caretaking behavior, and synthetic oxytocin has been used to treat depression.
