And things frequently go wrong. Ambulances are wired with dashboard computers, high-tech radios, navigation systems and phones -- all of which must be used by the EMTs while weaving in and out of traffic at top speed and blasting through stoplights like they're being chased by the Batmobile.

All of this adds up to a potentially chaotic driving experience, particularly when you consider that many drivers make no attempt to clear a path for rampaging emergency vehicles, because The Adventures of Tin-Tin starts in 15 minutes and goddamn if they're going to miss all the previews.

"If he doesn't move in three seconds, he becomes a passenger."

According to one study, EMTs in the United States have an estimated fatality rate of 12.7 per 100,000 personnel (more than double the national average), with the worst coming when riding in the patient compartment. Another study tallied the destruction caused by 339 ambulance crashes, totaling a shocking 405 fatalities and 838 injuries. That averages out to more than one person killed in every ambulance wreck. We're pretty sure goddamned jet packs are safer.

One center estimates they receive about 10 calls an hour that are of the completely stupid variety, including a person calling 911 because someone had smeared their doorknob with Vaseline and they were afraid to touch it. Other calls included asking for directions to the mall, the start date of daylight savings time and whether to use hot or cold water to do the laundry. But even when the operator decides the call is ambulance-worthy, it's often because the caller has an ulterior motive. People wind up manipulating ambulances as a sort of taxi service, thinking that taking the ambulance to the hospital will get them to see a doctor faster without an insurance check.

"Congratulations, clever man, you've hacked the U.S. health care system."

The truth is, people will be triaged in the emergency room regardless of whether they came in an ambulance, a car or a huge truck shaped like a hot dog. If the ambulance took you to the hospital for an earache, you won't see a doctor before the guy who walked in bleeding like a Japanese horror movie. But people do it anyway.

Some people who call 911 for non-life-threatening reasons do so a couple times a week or even multiple times in one day. Industry experts are calling the chronic abuse of EMS the 911 "safety net" system, wherein people struggling with headaches, toothaches and even feelings of loneliness call 911 because they have no one else to talk to. Wait, are we crazy, or is there a fortune to be made from a service that does nothing but listen to people complain on the phone for a small fee? Get us in contact with some investors.

"Oh, she's fine. We're just taking her out to pick up some groceries."

It does not take a Conan Doyle level superdetective to figure out that medical professionals get extremely stressed from their jobs. When you have an erotic three-way with life and death on a daily basis, you're going to need to take a break every so often for someone to finish crying (at least that's how our three-ways go). However, the degree to which EMTs experience this is worse than you can imagine.

"Sir, if you're going to die, you need to let me know, because I just can't deal with that crap today."

EMTs will almost always experience burnout, which is defined as "exhaustion of physical or emotional strength or motivation usually as a result of prolonged stress or frustration." It's because EMTs are routinely exposed to five unique stressors: high levels of uncertainty, high interpersonal tension, frequent exposure to human tragedy, extreme fear and a heightened physical response to the sound of an emergency alarm, which basically means that after working so long around emergencies, your body goes into overdrive whenever you hear an alarm.

"Sorry, dude. Someone's car alarm went off and I just flipped out."

And they can't just kick back and take it easy for a while; many EMS organizations are understaffed, meaning everybody has to work monstrous amounts of overtime. But even if they don't work overtime, most services run in 12- or even 24-hour shifts. Exhaustion and sleep deprivation are part of the job, sort of like being in rehab, only without any methadone or impromptu visits by Gary Busey. Workers will get suspended without pay for falling asleep on the job, even though they are required to work superhuman shifts.

"It's much safer for you to be constantly exhausted or methed out than to allow occasional naps."

The impossibly stressful long hours take a serious toll. Rates of post-traumatic stress disorder are higher than 20 percent among EMTs, and high-risk alcohol and drug use rates may be as high as 40 percent. So if your EMTs seem a little strung out, go easy on them. After all, if all of the crashes and frivolous calls and puking/bleeding/screaming patients don't get to them, they also have to deal with the fact that ...

Also, the patients are changing. Specifically, they are getting fatter. A heavy patient is going to need the same kind of attention as an average-size patient, but the methods must be altered dramatically, much like the Boba Fett costume the aforementioned heavy patient purchased from eBay last Halloween. Crews have had to completely rethink logistical problems with getting obese patients out of buildings with narrow halls, doors and stairs without everyone on the crew throwing their back out. It also means new equipment, as ambulance services across the country have to buy vehicles with specialized cots, ramps and winches to lift patients weighing between 350 pounds and Mighty Joe Young.

In case of emergency, the winch is made of chocolate.

The ambulances themselves have to change to accommodate this, too -- they have ushered in the use of bariatric ambulances, or "fat trucks." These are designed to be double-wide to accommodate heavier passengers, or as this article literally stated, "to ferry the most obese."

And they're occasionally used to render aid to beached whales.

But nothing you see there addresses the difficulty of removing a patient weighing just shy of a ton from the seventh floor of an apartment building when they literally cannot even fit through the doorway. Presumably at this point, the EMTs just start a controlled blaze in the lobby and let the fire department come figure it out.

You might expect EMTs to be relatively safe when dealing with patients -- after all, they are there to help. But in fact, EMTs face a lot of danger in the field, and they do so without the weapons and authority that police officers have. EMTs have been hit with cinder blocks, stabbed by syringes (often still filled with drugs), chased by dogs and shot at on a regular basis. In Boston, for instance, 28 percent of total EMT injuries in 2006 were the result of violent assaults.

"Sir, we're here to help. I'm gonna have to axe you to put that down."

One study conducted in 1999 found that, over a 12-year period, each paramedic involved was assaulted an average of nine times, with the attacks reading like a laundry list of every injury sustained by Christopher Lambert in The Highlander, including "170 cases of blunt trauma, 73 lacerations, two gunshot wounds, 10 stabbings, one burn, eight fractures, nine dislocations, one choking and 56 cases of miscellaneous body injuries."

Not all of them are work-related.

Sure, part of it is because they have to plunge into the bad parts of town no matter what time of night. But even in the nice parts of town, they're still not safe, and it's often because of the patients themselves. Sometimes patients are panicking, sometimes they're drunk or high or in shock. And of course, sometimes they're just insane.

And it isn't just the patients who can pose a threat to an EMT -- they can encounter hysterical family members and violent bystanders who attack them out of misplaced blame and rage. At which point we're assuming the universal answer to them is "Hey, just be glad this ambulance hasn't exploded yet."
