As we discussed in Chapter 1, when you exercise, your muscle cells take in molecules of oxygen and give off molecules of sweat, which work their way to your armpits. For your cooling-down phase, lie on your back with your arms laced behind your head and your elbows on the floor, thus exposing a maximum of armpit area and allowing the sweat molecules to escape into the atmosphere as harmless BO vapors. This would be an excellent time to start worrying about nuclear war again.

In this chapter, I can give you only a cursory overview of running, which is without question the most difficult and complex form of exercise, as is evidenced by the fact that it is the subject of numerous lengthy books costing upward of $14.95. Unfortunately, many members of the general public still labor under the dangerous misconception that running is simply a matter of getting out and running. So before you attempt to do any actual running, I strongly urge you to read a minimum of several books on the subject and to take lessons from a trained running instructor. I also cannot overemphasize the importance of spending large sums of money.

Running is the ideal form of exercise for people who sincerely wish to become middle-class urban professionals. Whereas the lower classes don’t run except when their kerosene heaters explode, today’s upwardly mobile urban professionals feel that running keeps them in the peak form they must be in if they are to handle the responsibilities of their chosen urban professions, which include reading things, signing things, talking on the telephone, and in cases of extreme upward mobility, going to lunch.

That’s why at the end of the working day, when the lower classes have passed out facedown in the Cheez Whiz, you can drive down the streets of any middle-class neighborhood in America and see dozens of professionals out running with determined facial grimaces, burning off calories, improving the efficiency of their cardiovascular systems, increasing their muscle flexibility, and ultimately staggering off into the bushes to die. Even as you read these words, thousands of designer-sportswear-clad bodies are rotting in the bushes of suburban America, and the only reason you don’t hear more about it is that the next of kin generally don’t report the disappearances, because they are quite frankly pleased that they no longer have to listen to the runner blather on and on about his or her cardiovascular development.

Of course, not all runners die in the bushes. Many fail to make it that far, because of knee injuries. To understand why, let’s look at the interior of the human knee.

What we can learn from this is that, although from the outside your knee feels like a croquet ball inserted in the middle of your leg, it is in fact a complex organ consisting of bone, muscle, thong, and mucilage, bounded on the west by Spain. The knee provides adequate support for everyday activities, such as renewing magazine subscriptions or gesturing at cretins in traffic, but it is not designed to withstand the strain placed on it by running, where each time the runner’s foot hits the pavement, the knee is subjected to 650,000 kilocycles of torque, and even more if the runner has been dropped from a helicopter. This is why it is so very important to choose the right running shoe.

Time was, of course, when there were no running shoes, only “sneakers,” which were bulky objects that cost $12 and said “U.S. Keds” on the side and had essentially the same size, weight, and styling characteristics as snow tires. But today’s topflight running shoe is a triumph of sophisticated, computer-designed, laser-augmented, fully integrated, infrared, user-friendly technology and space-age materials, packed with dozens of medically proven health and safety features, and all combined into a small and lightweight unit that, surprisingly, costs no more than a black-market infant.

Most running experts and bankers recommend that you wait until you’ve completely paid for the right running shoe, including insurance, before you plunge in and buy the left. When you do, I urge you to shop around for a shoe that is as similar as possible to the other one, except in so far as which foot it goes on. This is assuming that you intend to wear both shoes simultaneously.

You should, of course, wear a specially designed $200 Running Garment made from a synthetic material that has a name like the leader of a hostile reptilian alien invasion force in a space movie, such as “Gore-Tex.” The beauty of these materials is that they actually “breathe.” Really. At night, if you listen very carefully to your closet, you’ll hear your garment in there, breathing and occasionally chuckling softly at some synthetic joke it heard from your dress slacks.

One good place to run is in the Olympic marathon, because (a) you have to do it only once every four years, and (b) you have an armed motorcycle escort, so if people try to thrust liquids and fruits at you, which is a common problem in marathons, you can order your escort to fire a few warning rounds into their chests. The big drawback with running in the marathon, however, is that you have to consort with a bunch of sunken-eyed running wimps, some of whom are not even United States citizens.

This is why many people prefer to run, unescorted, on the streets of their own neighborhoods. The big problem here is dogs, which will view you as an intruder and may attack you, especially if they can smell fear on your body. This is why the wise runner carries a small spray can of a chemical originally designed for use by mail carriers. If a dog attacks, you simply spray this chemical into your nose, and within seconds you don’t feel any fear of any damn dog. Be careful that you don’t stare directly into the sun.

Mankind’s need to compete in sports goes back to that fateful prehistoric day, hundreds of thousands of years ago, when a primitive man first picked up a club and a primitive ball fashioned from animal hide, tossed the ball aloft, then whomped the club into the sloping forehead of a primitive umpire. Since then, there has never been a civilization that did not engage in sports. Archeologists digging in what was once ancient Sumeria recently found the remains of a primitive stone jockstrap. This goes a long way toward explaining why you see so few Sumerians around.

In ancient Greece, the Olympic games were considered so important that when it was time to hold them, the Greeks would lay down their arms and invite their enemies to do the same. Then the Greeks would snatch up their arms again, whack their enemies into pieces the size of candy corn, and celebrate by having the Olympic games.

Back then, of course, the only events were running naked, jumping naked, throwing things naked, and ice dancing. Today, we have hundreds of sports to choose from. In this chapter we’re going to look at some of the more popular modern sports, so you can choose the ones you wish to incorporate into your overall fitness program. As I have stressed repeatedly throughout this book, before you embark upon any new form of physical activity, you should notify your doctor’s answering service.
