6 tips for minimizing cell phone radiationEditor's note: Last summer, this article was one of the most popular on the Chart. We're republishing to share these important tips again with you. Scientists at the World Health Organization list mobile phone use in the same "carcinogenic hazard" category as lead, engine exhaust and chloroform. There haven't been enough long-term studies to make a clear conclusion if radiation from cell phones is safe, but there was enough data to persuade the WHO of a possible connection to make them upgrade the category in May 2011. Cell phones use non-ionizing radiation, which doesn’t damage DNA the way ionizing radiation does. The cell phone radiation operates more like very low power microwaves, but nobody really likes to think of leaning their face on a low-powered microwave. If the WHO’s labeling of cell phone use as "possibly carcinogenic to humans" has you alarmed, here are some quick basic tips to limit your exposure.

Spend money mindfully to stress lessEditor's note: CNN contributor Amanda Enayati ponders the theme of seeking serenity: the quest for well-being and life balance in stressful times.
In poll after poll, Americans say that the state of their finances is one of the biggest sources of their stress. “People are spending money they do not have to buy things they may not need,” observed Tony Wagner, Innovation Education Fellow at Harvard’s Technology & Entrepreneurship Center and author of “Creating Innovators: The Making of Young People Who Will Change the World,” during our recent interview. While researching his book, Wagner discovered that more than 70% of our economy is based on consumer spending. Increasingly, over the last 20 or so years, that consumer spending has been fueled by debt. The savings rate in 2007, immediately before the economic collapse we are still slogging through, was negative 2%. That kind of spending is unsustainable, said Wagner, “economically, environmentally and spiritually.”

Tools you'll need for your first triathlonYou don’t need any fancy triathlon-specific gear to finish a triathlon. A swimsuit, any bike (and helmet) and pair of running shoes are really all it takes. But there are limitless triathlon accessories (triathlon cufflinks, anyone?) if you want to look sharper, go faster or be more comfortable. Consider your race goals before pulling out the credit card. I want to finish Instead of relying on questionable tires, swap them for a new set designed for durability, such as the Specialized Armadillo or Continental Gatorskin. After equipping your ride with dependable tires, take it to a mechanic to check the chain, derailleurs, shifters, bolt tension and cables before race day.

Lasers may one day replace X-RaysResearchers at the University of Colorado have made a breakthrough that may one day help doctors detect disease earlier and with more accuracy. Based on the hypothosesis of Dr. Tenio Popmintchev, researchers have created a laser beam by adding 5,000 photons together. Previously, two photons were typically used to create laser beams. This is the first time so many photons have been successfully added together. The result is a more efficient and easier to set up X-ray, according to Dr. Margaret Murnane.

'Life begins at the end of your comfort zone'Editor's note: Nancy Klinger is one of seven CNN viewers training for the Nautica Malibu Triathlon with CNN's Dr. Sanjay Gupta. Recently Klinger and the rest of her teammates traveled to Hawaii for a week of intensive training. How and when it happened, I have no idea, but at some point many years ago, after starting a full-time job, getting married and having two kids, I lost my sense of self. My list of priorities did not include me. Everyone and everything were well-taken care of, except me. My life revolved around just getting the daily tasks done. Even the pets were given a higher priority than me! During this period, I also became very boring. I stopped playing tennis and stopped being active - things that had always brought me great joy. I rarely went out with friends. My look was boring, my clothes were boring. But, I was always the go-to person if anyone ever needed anything. My life continued on day-by-day in some sort of strange comfort zone (really a rut). Since the start of my Fit Nation journey, I have become a completely different person - a better person, much more confident, much more at ease with life and with a renewed sense of purpose. |
