Today is an exciting time for nurses. The job market is plentiful with positions including the demand for traveling nurses. To be a travel nurse takes a special person. The individual who is a travel nurse is one who likes to see new places and meet new people, face challenges with confidence and work as a team member. Being a travel nurse is not for everyone.

A sexy pair of legs moseys its way down a soft, vacuumed carpet, around a bend, and through a long, narrow aisle.

Suddenly, these shapely stems, which are encased in bright spandex, dissolve into a jungle of many others, instantly blending into the vibrant surroundings like chameleons. The long row of gams seems endless. They're shaking, they're baking, they're working like jackhammers - together in harmony - as if they were all drilling for oil.

In a way, he's a lot like Edgar Allen Poe.

The famous writer had been deceased for many years before he miraculously cracked super-stardom, his once-buried work revamped from the ashes to be relished by millions and millions of literature fans.

Well, Joseph Pilates is not Edgar Allen Poe. The German immigrant is hardly a household name in 1999, but just like Poe, some thirty-two years after his death, his lost treasures are now being discovered as genius works of art.

The sweat is pouring down by the bucket. Your hair is soppy and wet. Your eyes are popping out of your head.

Meanwhile, the only pounding worse than the one on the floor is the one on your joints.

Your knees, your ankles, your toes, they all feel like they're two centuries old. The agony is shooting furiously throughout every limb in your body.

It was a humbling moment, indeed.

At the time, I felt like I was higher than a mountain. I was running five miles every morning, laboring through a hard day of strenuous work every day, then hitting the gym every night. I could rip out pushups in three-digit sets, grind through a set of 60 dips without cracking a single sweat gland.

Meanwhile, my strength remained in tact.

You peek into the aerobics room on your way out the door and see that they're kicking up a storm in there. At first, they look like either an array of Rockettes or a Broadway dance audition. Knees are pumping, legs are snapping, and feet are flying everywhere.

And let's not forget the sweat. It's pouring down by the bucket.

Sure, to the curious on-watcher, it would be difficult not to be swept up into the most publicized cardio craze to capture the nation in nearly two decades.

Walk, don't run, to your local fitness store and try on a pair of walking shoes.

For cardiovascular fitness, there isn't an activity that's more sensitive to the wear and tear of your body than a stroll through the park. Aside from being a tremendous tension releaser and a great metabolism booster, walking is a great exercise to strengthen your legs, abdomen, and heart.

Up and down. Up and down. Up and down.

This may sound like either your ongoing battle with the bulge or perhaps a friend who is on heavy doses of Prozac.

But the never ending elevator ride known as the step machine can be a great tool for your fitness and weight loss endeavors. Step machines, otherwise known simply as "steppers", have become very popular devices in health clubs and gyms throughout the country.

It's a fact that every day, cells in your body divide, grow and die. Most of the time they do it in an orderly manner. But sometimes they grow out of control. This type of cell growth forms a mass or lump called a tumor. Tumors can either benign or malignant.

Benign tumors are not cancerous. But left untreated, some can pose a health risk, so they are often removed.

The causes of breast cancer are not completely understood, although it is clear that a woman's age, gender and lifetime exposure to estrogen and her age at the time of her first childbirth can play an important role. Because no one knows exactly what causes breast cancer, there is absolutely no way to prevent it. However, there are steps that every woman can take that may make developing this cancer less likely.
