VITAL SIGNS Beyond the Blues “Everything was fine” for this salesman, but he couldn’t shake his funk. His hormones may have had something to do with it. DOUGLAS G. ADLER HISTORY LESSONS Cracking the 414s In 1983, a group of young adults from Milwaukee became famous for hacking into several high-profile computer systems, introducing the country to the world of cybercrime.

Wilderness The great outdoors is good for our overall health, but this precious resource is in danger. JONATHON KEATS HOT SCIENCE P. 9 Saving the mangrove tree and the white-cheeked gibbon, the first image from Solar Orbiter’s mission, meat’s role in humans’ diets, the best science books to read now and much more. COLUMNS & DEPARTMENTS p. 10 p. 66 66 p. 54 BOULDER, Colorado The U.S. government has engineered the most ingenious, most accurate clock in the world: the F-1 U.S. Atomic Clock in Boulder, Colorado. Our extraordinary new Stauer Titanium Atomic Watch utilizes the transmissions directly from that remarkable cesium fis- sion atomic clock to report the most precise time. This scientifically advanced timepiece will gain or lose only one second over a 20 million-year period. It is that accurate! This perfectly tuned technological invention with the super light strength of titanium is now available for UNDER $130. Super Light Titanium has two big advantages over steel. One is corro- sion resistance and the other is that titanium has the highest strength-to-weight ratio of any metal, which means that titanium is approximately 45% lighter than steel. But every other titanium watch that we can find is priced at over $400, and none of those are nearly as accurate as our atomic movement. Stauer has decided to bring these resources together in a timepiece that has the most accurate movement available today. You’ll never have to set this watch. Just push one of the buttons and you are synchronized with the atomic clock in Colorado, and the hands of the watch move to the exact time position. The sleek black textured dial has luminous hands and mark- ers plus the timepiece is water resistant to 3 ATM. A Titanium-clad offer. This Titanium Atomic Watch exceeds the accuracy of any Swiss luxury automatic so you can be more punctual and keep most of your money in your wallet, not on your wrist. Look at your watch and we guarantee that the time is incorrect, unless you are wearing the advanced atomic technology. The Stauer Titanium Atomic Watch is not available in stores and it comes with our 30 day money-back guarantee. If you’re not completely satisfied with the accuracy, simply return the watch for the full purchase price. Includes a 2-year warranty on the movement.
