The Super-Sized Generation

Health professionals are in increasing agreement that childhood obesity will become one of the top future health crises in the US. Today, two-thirds of all Americans -- and one-third of American children -- are overweight. Obesity, as we all know, leads to a host of serious health problems, like diabetes and hypertension, as well as secondary socioeconomic problems such as escalating healthcare costs and lower workplace productivity. In fact, it will soon overtake smoking as the leading cause of preventable death. For young people, obesity has become such a problem that some are undergoing surgeries to help them lose weight. For obese kids, it's not a matter of vanity; they're literally trying to save their lives.



So how did we get to this state, and how can we turn things around? Health reporter Lisa Tartemella suggests that the problem has many root causes, including:



  • Larger portions served at fast food outlets and convenience stores (some large sodas are close to a half-gallon in size)
  • TV viewing, which leads to less exercise and more exposure to commercials for junk foods
  • Families with two working parents, who don't have time to cook balanced meals
  • Schools, where food quality is often poor, and physicial activities such as gym and recess have been cut back


Tartemella also says that low-income households are more at risk of obesity, because they are often in neighborhoods where it's not safe for kids to go out and play, and rely on less-expensive fast foods.



One of the major debates about obesity in the coming years will be how to approach it. Traditionally, body weight has been a matter of personal responsibility. After all, no one can force you to work out or go on a diet. But there are growing calls for more of a national policy on the issue, especially in areas where government has the most clout, such as schools. More awareness is also in order, although most of us have supposedly been taught healthy eating habits from childhood, and we can all read the nutrition facts on the foods we buy.



Will obesity become such a public health crisis that we'll hear calls for regulating the food industry, controlling fast-food advertising, or even for banning certain food types? Not in this decade... or at least in this administration. But things could change if the perception grows that obesity -- and the strain it puts on society at large -- is out of control.

Butthead Lake

For our Friday afternoon diversion, we take you to Washington State, where Census Bureau record now list the name of Bevis Lake, 25 miles north of Seattle, as "Butthead Lake."



OK, so Beavis and Butthead was one of television's great accomplishments... But c'mon now!



It's not all bad, though. Who wouldn't want to spend their vacation fishing and swimming in beautiful Butthead Lake?

"Someone at the Census Bureau must have gotten bored and made a joke out of naming the lake, said Ken Brown, a land surveyor with the state Department of Natural Resources."

Your tax dollars at work...

The 2038 Bug

Depending on your point of view, the Year 2000 (Y2K) "bug" was either a lot of hot air, a shining example of crisis prevention, or a major disappointment (especially if you sold your home to buy dehydrated food and guns). But now, there's another data "bug" on the horizon.



It's being called the "2038 bug," and it's caused by how computers measure Coordinated Universal Time (UTC), a global time standard. Modern computers calculate UTC by counting the number of seconds that have elapsed since Jan. 1, 1970 (sometimes called the "Unix epoch," as this method was originally developed for Unix), storing it as an integer instead of a calendar date. As of the moment of this posting, 1,105,118,249 seconds have elapsed since the Unix epoch. This is a stable and reliable way of keeping time... and is one reason why most computers were unaffected by Y2K.



But what happens when the date integer grows too large for computers to manage properly? There was some concern that this would be a problem on Sept. 9, 2001, when the Unix epoch passed the one-billion-second point. The next milestone, however, will occur when the amount of memory allocated for the integer is exhausted and the date could be corrupted.



Using this calculation, 32-bit computers will reach this date at precisely 3:14 AM GMT on Tuesday, January 19, 2038. The bug could cause the date integer to flip to a negative number, yielding a date of Friday, Dec. 13, 1901 (hence the bug's other name, the "Friday the 13th bug").



The good news, however, is that the bug is easily corrected by increasing the number of bytes dedicated to storing the date (already done in 64- and 128-bit architectures). Also good news is that we have 33 years to upgrade our systems.



To check your computer's vulnerability to the 2038 bug, run this script.

Online Holiday Spending Up 24% in 2004

Although the jury is still out regarding the success of this past holiday retail season, online retailers have something to smile about. In line with expectations, online sales increased by 24% during the 2004 holiday season over the year before. US consumers spent a whopping $8.8 billion online during the holidays.







Entertainment, apparel, jewelry and electronics were the big winners, along with the relatively new category of photo printing and sharing. In addition, consumers generally spent more online than the year before, and bought more big-ticket items. According to VeriSign, the average online purchase this season was $145, with the daily average peaking at $178 on Dec. 22, 2004.



One question sure to be examined closely in the coming weeks is how deeply online sales cut into brick-and-mortar retail. So far, holiday sales figures have been mixed; "big box" retailers report disappointing sales, whereas more upscale retailers had a merrier season. Exactly where online sales fall into the mix will be a matter of great importance, particularly if consumers prove to be abandoning traditional stores for cyberspace.

Tsunami-Damaged Ecosystems Could Take Years to Recover

Overshadowed in the coverage of the human toll of the south Asian tsunami is the damage it did to the region's delicate ecosystems. Animals and plants dwelling on the shoreline were the worst hit, as were the fragile coral reefs and mangrove forests.



Coral reefs in the Maldives were completely destroyed. These will take decades to recover, as coral grows at only 1/2 cm (less than 1/4") per year. This will have a direct impact on the area's economy, as the diving resorts that grew up around these reefs may not rebound anytime soon.

Blogging Comes of Age

Anyone who hasn't been living on the moon for the past year knows that the blogosphere is the place to be. And now it's been made official, through a report from the Pew Internet and American Life Project. The report states that blog readership rose by 58% in 2004, and that blog traffic now comprises 27% of all Internet use. Bloggers and blog readers are also a diverse lot, with a broad spectrum of age groups, as well as many women and minorities active in the blogosphere.



These findings have prompted a lot of discussion as to whether blogs are literally ready for prime time. That is, can they make the leap from a hobby to credible media resources that can sustain readership and even make money? If you think that another dotcom boom is in the making, you may want to think again.



From the advertising perspective, skepticism abounds. Observers point out that many of the hottest blogs are too controversial for most mainstream marketers, are often openly hostile to the very businesses that are prime advertisers. Plus, useful metrics still don't exist that would allow advertisers to measure their reach and determine accurately what they're getting for their ad dollars.



Tempering the growth in blogs are other statistcs, such as Pew's findings that only 5% of Internet users they surveyed used RSS aggregation, and that over 60% had no idea what a blog was. The Perseus Blog Survey, moreover, found a high rate of blog abandonment, noting that 66% of the blogs they surveyed had not been updated in over two months.



Blogging is coming of age, all right. But it still has to go through a rocky young adulthood.

Get Ready for More Disasters

In an effort to brighten everyone's day, an article in the New York Times suggests that the Dec. 26 tsunami that struck south Asia may be indicative of more devastating and more frequent natural disasters.



The reason is not so much environmental as it is demographic. As populations in the developing world grow, they build on less-than-prime real estate that is more prone to natural calamities such as earthquakes, floods and drought. These areas are also congested and unsanitary, promoting the spread of contagious diseases. And unlike the developed nations of the West, these populations don't have the resources to implement safety measures such as earthquake-proof structures, flood controls and early-warning systems. Even if they did, their political infrastructures might not be able to make use of them.



As the recent tsunami showed, the world needs to place a priority on prevention, through better monitoring, civic planning and emergency preparedness. We won't be able to stop the next earthquake or tsunami, but we can act to save lives.
