bluetooth headsets make up one of the fastest wireless markets here in the US and around the world. headsets with bluetooth wireless technology are capable of working with a variety of other bluetooth enabled devices such as cell phones, pdas, and digital music devices (like the iPod). Unlike conventional headsets, bluetooth headsets do not require wires of any sort, but rather receive information from your portable device through 2.4GHz radio waves. The range of communication for most headsets is somewhere around 10 feet, which is usually plenty long.

not surprisingly, there are a wide variety of bluetooth headsets out there, and it really comes down to tastes in styles and preferred features as to which one is right for you. You'll want to make sure, for instance, that your bluetooth device - whether it be an iPod, laptop, or pda - will work with your chosen headphones. Here we list below some of the most popular bluetooth headsets and their relevent features.

Obesity is on the rise; more and more of us should shout out "No thank you, I do not want any fries with my meal. Obesity means having too much body fat. It is different from being overweight, which means weighing too much. Both terms mean that a person's weight is greater than what's considered healthy for his or her height. BMI, a standard measure to determine obesity, is calculated using weight and height.

A BMI of more than 25 is considered overweight, and more than 30 is obese. Obesity occurs over time when you eat more calories than you use. The balance between calories-in and calories-out differs for each person. Factors that might tip the balance include your genetic makeup, overeating, eating high-fat foods and not being physically active.

The bad news

Being obese increases your risk of diabetes, heart disease, stroke, arthritis, eye disease and some cancers.

The good news

If you are obese, losing even 5 to 10 percent of your weight can delay or prevent some of these diseases.

Blame it on Mom

A study by Dr. Mary Beth Terry at Columbia University in New York City of a group of 261 women born between 1959 and 1965 found that the amount of weight a woman's mother gained during pregnancy influenced her risk of being overweight at age 20 with every 10-pound increase in weight gain associated with a 65 percent greater likelihood of being overweight.

But maternal pregnancy weight gain had no effect on whether or not a woman would be overweight at age 40, suggesting that current environmental factors had a greater influence.

Mom's body mass index, as well as her own birth weight, also influenced the likelihood that the daughter would be overweight at age 20, but not at age 40.

Rapid weight gain between one and seven years of age was the only factor to influence obesity risk at both time points.

Given that people today are heavier than they were four decades ago, and that women tend to gain more weight during pregnancy (averaging 30.5 pounds in 2003), compared to 22 pounds in the early 1960s), "these trends all point to dramatic long-term consequences for the prevalence of overweight in adulthood", Terry and her team note.

Nevertheless, she added in an interview, the finds should not be interpreted as discouraging women from gaining enough weight during pregnancy. "Having a healthy weight gain and having a healthy size baby at birth is very important for reducing infant mortality." Terry said. Obesity Linked to Eye Disease

Scientists have found a link between obesity and a range of eye problems, including glaucoma, which can lead to blindness.

They say it is common knowledge that expanding waistlines are linked to conditions such as diabetes, heart disease and cancer.

Now opticians warn the prospect of eye disease should also be a powerful incentive to lose weight.

Professor Michael Belkin, professor of ophthalmology at Tel Aviv University in Israel, found a link between obesity and four eye diseases that cause blindness, age-related eye degeneration, cataracts, glaucoma and retinopathy.

"While this is something that most ophthalmologists know, it's not common knowledge and it should be."

"It's the risk factor that no one talks about."

BMI and colon cancer

NEW YORK (Reuters Health) - For men, the risk of colon cancer increases with body weight in a nearly linear manner, a study shows. For women, the risk is more variable but still trends upward, particularly for those younger than age 67.

The findings highlight the importance of weight control for colon cancer prevention, Dr. Kenneth F. Adams, of the National Institutes of Health in Rockville, Maryland, and colleagues conclude in a report in the American Journal of Epidemiology.

They examined the association between body mass index (BMI) and colorectal cancer incidence in 307,708 men and 209,436 women enrolled in the NIH-AARP Diet and Health Study.

For anyone living in the Natal Midlands, or to be politically correct, the KwaZulu-Natal area of South Africa, the last week of June 2007, will be remembered for many years to come. The extreme weather conditions experienced in the area, led to total devastation, to many of the residents, mostly farmers and their staff.

As if the recent strike action by all government departments, hadn't already caused enough chaos in their lives, with the closure of schools, the disruption of mid-year exams, the evacuation of hospitals, the stoppage of any maintenance work and the desire of the police and prisons department to join the strike action, Mother Nature had the last word.

Friday, Saturday and Sunday were pretty hot, for this time of year and as usual, fire warnings were issued. It was normal in the dry conditions, to have several fires each day and the forestry industry in particular, are always on full alert, at this time, every year.

What was not expected, was the gale force winds, that developed and reached utterly devastating proportions. The winds started on Sunday night, but were not unusually strong. They continued throughout Monday, reaching some the highest speeds, ever recorded in the area, by Monday night. What started as normal fire warnings and alerts, soon became emergencies, as huge fires spread at terrifying speeds. Extra fire crews were brought in, to help control all these fires and just when the tired firefighters thought they had won the battle and could get some well deserved rest, the heavy winds started and transformed quiet, smouldering ashes, into raging infernos, that ran through plantations and grasslands, completely out of control. There were many stories of threatened families, burnt out houses and urgent evacuations. Thousands of Hectares were burnt out and families left destitute, particularly in the Underberg area and in the Karkloof, to Curry's Post area.

Imagine how pleased these people were, when it started raining on Tuesday. Most uncharacteristic for the month of June, those light rains, turned in to steady, harder rain, right through the night. What started as a welcome relief and the end to the fire dangers, now threatened those same people, who had been left homeless. The rainy conditions continued and the highest rainfall ever recorded in June, turned to cold and misty conditions. Farmers were now unable to repair damaged fences and buildings, animal carcasses that were caught in the fires could not be removed and their staff, were unable to find dry and warm conditions, in their fire ravaged homes.

But, Mother Nature was not finished yet. These poor people woke up, the next morning, to snowfalls. The snow continued and some of the heaviest falls in history, were recorded. It even snowed in Johannesburg, for the first time in 26 years! Many people, already left homeless, were now forced to contend with freezing conditions. All of this, in the space of only one week!

The area was declared a natural disaster and the army was called in, to assist with tent towns, feeding schemes and to facilitate the disposal of the dead animals. In one incident, eight horses were trapped by fences and a bulldozer was, through the terrible heat, unable to get close enough to help them escape. They all perished in the fire. Apparently the heat was so severe, that the deep root structure, of trees and plants and grass, was so severely affected, that it will take several years to mend.

There is no doubt, as to who is in charge, in this world and it certainly isn't man! What causes these extreme conditions and why? Well, the people of the Midlands, will be asking this question, for some time to come. From hot Summer weather, to extreme winds, to heavy Winter rainfall, to heavy snowfalls and then to bitterly cold conditions, all in one week, has really taken it's toll on the area, but fortunately no known human deaths, were reported.
