Dear Lifehacker, Sincerely, Dear Harold, You might have heard of the Body Mass Index (or BMI), the metric that is frequently used to measure “body fatness.” It’s important to note that this isn’t always the best metric, but it’s an easy one to determine, which is why many doctors default to it. However, as obesity physician Dr. Spencer Nadolsky explains, it does have some limitations: A lean young male with a BMI of 27 is very different from an abdominally obese post-menopausal female with the same BMI. BMI doesn’t take many things into account, such as muscle mass. If everyone could get their body fat measurements taken via DEXA, doctors would just use that, but that isn’t always feasible. As Dr. Nadolsky mentioned, body fat percentage is a much better metric to use. For example, my BMI is 28, which is only two away from obesity, but I’m not overweight, because I have a relatively low body fat percentage. This number is difficult to … [Read more...] about Can I Be Overweight and Still Healthy?

Ed Bott Yes or No Robin Harris Best Argument: Yes List of Events: Opening Statements Rebuttal Closing Statements The moderator has delivered a final verdict. Opening Statements A recipe for success Ed Bott: Apple has been kicking ass in the high-end portable PC market over the last couple years. The MacBook Air has become deservedly popular for its exquisite engineering. But that’s all about to change. The pieces are finally clicking together for PC OEMs to make small, light, great-looking portable PCs at commodity prices. That is historically when the Apple versus Wintel battles get interesting. In this economy price is more of an issue than ever, and economies of scale should drive the price of ultrabooks down quickly. I predict ultrabooks will be a big hit with PC buyers who like the MacBook Air form factor but prefer Windows to OS X. The combination of genuinely interesting hardware and a mature, smoother, more reliable Windows should narrow or … [Read more...] about Can Wintel win the Ultrabook market?
For the teacher who went out drinking on a school night, or has a severe coffee deficiency -- here are some tips for using technology and keeping the little 'ones' happy in class. I've taught in a number of places and countries. From a typical, run-down west London high school, a VIP college in Azerbaijan, a private school in Rome, to a graffiti-covered basement 'classroom' in Austria. However, out of the 25 or so countries I have graced with my presence, I have found a universal rule useful in making lessons 'work' -- whether you've spent all night on a plan, or more likely have thought it up in five minutes on your cigarette break. (It's okay, I know.) The golden rule is -- anything visual, audio, or remotely funny, students love you for it. Whoever you are teaching, from future shopkeepers to juvenile jailbirds, anything that makes a student watch but not think too hard will be popular. The ones that want to work will take something away from it, the ones that … [Read more...] about How we really teach with tech in 21st century classrooms

GRAND PRAIRIE, Texas -- Without pausing, the Jeep-sized vehicle made quick work of the steep pile of rocks, its wide, knobby tires climbing the small hill with ease. Even more remarkable, the vehicle had no driver. Meet the Squad Mission Support System, or SMSS, a prototype Lockheed Martin project designed to help the military take the load off combat soldiers and Marines. Literally. 12 How robots can help soldiers haul their heavy gear (pictures) Soldiers and Marines often are forced to carry as much as 130 pounds of gear into the field with them. That weight, while comprising many different essentials -- food, water, ammunition, batteries, clothing, and so on -- can take a toll on their ankles, backs, and knees. One solution: transfer much of that gear onto autonomous vehicles that follow along with military units as they head out on missions. To date, the U.S. military has yet to formally issue a contract for such systems, but it has indicated its interest in … [Read more...] about This robot can take the weight off soldiers’ shoulders
