In case you hadn’t noticed, career colleges aren’t just for learning a vocational trade anymore. Nowadays, career colleges can help you obtain a Bachelor’s, Master’s, or even Doctorate Degree in just about any field of study, or they can even help you simply brush up on skills you might already have on your way to earning a certification or Associate’s Degree. So while some career schools might still specialize in vocational trades like auto body repair, masonry or hair styling, majority of today’s career colleges are designed to help working professionals meet their career objectives.

Prompted by an inviting and growing selection of career and online colleges, more adults are returning to school than ever before. Whether you’re seeking to advance your current career and education, break into a whole new field, or just enjoy studying something you’ve always wanted to, going back to school can be enjoyable and rewarding.

And yet, many potential students who could clearly benefit from enrollment at a career college are hesitant to do so. The reason? In too many cases, they are being held back by nothing other than their own fear.

The First Step is Admitting It

Let’s begin by getting everything out on table. Some reservations commonly heard from working adults who are considering a return to college include concerns that:

They won’t fit in It’s too expensive There isn’t enough time in day It will take forever to complete a degree Employers won’t view degree (or certification) as credible The coursework won’t be valuable or useful

In reality, just about any student who has attended a career college—whether online or on-campus—will tell you that there really isn’t anything to fear in a return to school. While they may have once had same fears as you do now, they learned very quickly that those fears were actually unwarranted.

By taking each fear one by one, we can begin to understand what these current students now know and how glad they are that they didn’t let their fears hold them back.

I’m Afraid I Won’t Fit In

It is common for a person in their thirties or forties to worry that they’ll stick out like a sore thumb in a classroom filled with “kids” from ages of 18 to 25. However, recent information from Census Bureau and U.S. Department of Education states that adult students are fastest growing educational demographic, revealing that 40% of college students are now 25 or older. Further information from National Center for Education Statistics points out that students age 35 and older rose from 823,00 in 1970 to nearly 3 million by 2001.

If you’re still worried about fitting in to classroom as an adult, a few facts that might help allay your concerns include:

With online learning, you’ll be working on a more individual basis and won’t have to worry about ‘standing out’ in a physical classroom; Many colleges, traditional or otherwise, have seen a spike in their ‘older’ students, and it’s likely you won’t be tiny minority that you expect; and Many older adults actually find it rejuvenating and refreshing to be in a classroom environment with a younger group that is eager to learn.

I’m Afraid It Will Be Too Expensive

Tuition…books…it all adds up. And many potential students get scared off by investment it requires to earn their degree. But key to overcoming this fear is to consider it as just that: an investment in your future. Think long term instead of short term. In almost every case, career advancement you will get after earning your degree will easily make up for upfront costs of attending school. Besides, many career colleges—especially those online—may be more affordable than you realize. Do your homework and weigh long-term benefits before deciding not to enroll in a school for this reason.

I’m Afraid It Will Take Up Too Much Time

For busy working adult, notion of taking on any additional endeavors can be downright stifling. It’s not always easy balancing work with personal life, and adding school on top of all your other responsibilities might seem virtually impossible.

And yet, it’s not. You’d be amazed at how much extra time you can squeeze into a day. Sure, there will be some sacrifices you’ll have to make, but if you just try watching a little less television, say, or letting your friends know that you won’t be able to make that barbecue next weekend, you’ll be amazed at how much time you can free up. Just remember to keep your eye on prize, and your sacrifices will all seem worthwhile.

In recent years there has been considerable discussion and concern about possible hazards of electromagnetic radiation (EMR), including both RF (Radio Frequency) energy and power frequency (50-60 Hz) electromagnetic fields.

All life on Earth has adapted to survive in an environment of weak, natural low-frequency electromagnetic fields (in addition to Earth's static geomagnetic field). Natural low-frequency EM fields come from two main sources: sun and thunderstorm activity. But in last 100 years, man-made fields at much higher intensities and with a very different spectral distribution have altered this natural EM background in ways that are not yet fully understood. It has been known since early days of radio that RF energy can cause interference in most of wireless operated systems and in devices which process extremely low power signals associated with control systems and in medical equipments. Very high density of Electromagnetic Fields have been known to have resulted in injuries by heating body tissue. These heat-related health hazards are called thermal effects. In addition, there is evidence that magnetic fields may produce biological effects at energy levels too low to cause body heating. The proposition that these thermal effects may produce harmful health consequences has produced a great deal of research. Human body nervous system is also known to work on extremely low intensities of electrical signals. Very little has been done to investigate effect of Electromagnetic Fields on human nervous and control system which as such leaves a lot of scope for future research.

Potential Sources of EMR The list could be endless starting with seemingly harmless AC (alternating current) operating devices to all intentional and non- intentional transmitters. Appreciable radiation occurs as size of components and connecting wires approaches one tenth of wavelength of operating frequency. The intensity of field so radiated also depends on power handled by device. To name a few tube lights, spark plugs, washing machines, music systems, power amplifiers, computers, lifts, air conditioners, cable TV, computer screen etc all fall in category of non-intentional transmitters but can be potential source of Electromagnetic Radiations. All radio and TV broadcasting systems, telecommunication systems and equipments, RADARS, mobile phones etc are intentional transmitters of Electromagnetic Radiations and may result in typical effects on various systems in addition to causing serious interference problems and affecting human body. With ever increasing use of modern digital technology in almost all modern processing and communication equipments threat of unintentional Electromagnetic Radiation is further enhanced. As all digital signals positively have a very large bandwidth, its increasing use will result in Electromagnetic Radiations in almost all frequency ranges there by leaving a possibility of affecting most of electronic devices and also human beings.

Some Typical Effects of EMR

Electromagnetic Interference: Interference is energy levels introduced by electronic or communications systems that have a detrimental effect on other systems. Any electronic system is capable of receiving Electromagnetic Radiations if size of components or connecting wires approaches one tenth of frequency that may be present in surrounding environment due to any intentional or unintentional transmitter. Depending on intensity of this unwanted received radiation there could be instances of malfunctioning of device receiving this energy. There have been number of instances where such a condition had resulted in catastrophic failure of equipments. The most famous example is failure of Electronic surveillance system installed at one of ships of United Kingdom Naval forces during Falkland war due to operation of its own Radar system installed on same warship. As a result of this only one system could be operated at one time resulting in loss of ship. Intentional Jamming of radio receivers by security and police forces is utilization of this effect to make enemies receivers inoperative, however it can also happen due to unwanted and unintentional Radiation of Electromagnetic fields.

Effects on Human Body: Body tissues that are subjected to very high levels of RF energy may suffer serious heat damage. These effects depend upon frequency of energy, power density of RF field that strikes body, and even on factors such as polarization of wave.

At frequencies near body's natural resonant frequency, RF energy is absorbed more efficiently, and maximum heating occurs. In adults, this frequency usually is about 35 MHz if person is grounded, and about 70 MHz if person's body is insulated from ground. Also, body parts may be resonant; adult head, for example is resonant around 400 MHz, while a baby's smaller head resonates near 700 MHz. Body size thus determines frequency at which most RF energy is absorbed. As frequency is increased above resonance, less RF heating generally occurs. However, additional longitudinal resonances occur at about 1 GHz near body surface.

Health Care Engineering: Is electromagnetic Interference (EMI) becoming a problem in healthcare environment? Although electrical interference in hospitals is often regarded as no more than a minor nuisance, there are documented cases in which equipment failures due to Electromagnetic Interference (EMI) have lead to injury or death. Some examples fare as follows: - • In 1992, a patient attached to a monitor-defibrillator in an ambulance died because of interference from ambulance radio prevented machine from working (1). • In 1987, patient monitoring systems failed to sound alarms because of interference; two patients died as a result (2).

• In 1993, a patient fitted with a pacemaker went into ventricular fibrillation shortly after being scanned with a metal detector outside a courtroom (2).
