Not everyone is made for an office job. In fact, some people only flourish when they're testing their mettle in high-risk, high-energy situations where anything could go wrong at any time. Does this sound like it describes you? If so, here are four electrifying careers that will keep you on your toes.

Firefighter

Firefighting is one of the most dangerous jobs on the planet, so it's also one of the most exhilarating. Not only will your bravery save people and pets from all walks of life, but you'll also be pushing against your limits every single time that you run towards a fire. Are you up to the challenge? Can you get the job done despite a racing heart that leaves cold sweat on your neck? Look into firefighter jobs and find out.

Animal Training

While it's true that the circus isn't as popular as it used to be, animal training is still a big business in zoos, wildlife shelters and safari reservations around the world. You can even find animal training jobs for big-budget Hollywood movies if you want a taste of glory with your danger. Whether it's herding an elephant or teaching a lion to roar on command, this career is one that's full of action, so it's a great match for anyone seeking high-octane thrills.

Aviation

A career in aviation will bring you closer to the sky than most human beings even dream about. While the most popular aviation careers usually involve flying, you can also find excitement as everything from an air traffic controller to an aeronautics specialist. Some schools, like the Institute of Aviation at Parkland College, know that pilots aren't the only adrenaline junkies in the aviation industry, so you'll be among like-minded individuals when you join their ranks. As a bonus, that joining can come in many different forms with many different employment opportunities.

Emergency Room Doctor

This job doesn't involve wrangling tigers or rushing into burning buildings, but lives are on the line all the same. As an emergency room doctor, you'll be expected to handle accidents, injuries, sicknesses and surprises of all kinds, often with very little warning and no time to second-guess yourself. This isn't a career for the faint of heart, but if you're good under pressure and ready to tackle the challenges of modern medicine, consider a job in the ER.

These are just four careers that will get your blood pumping. They're also careers that will help people, so you'll be doing something meaningful even as you indulge in the biggest thrills that the world has to offer.
