...many as 10 to a depth of up to 15 m. The frigid waters don't dampen the thrill of swimming among humpback whales, leopard seals and penguins. Visibility is excellent, and spectacular marine life like sea stars, brittle stars and coral puts on a stunning display. In optimum ice, water and wind conditions, groups may dive as many as four times in two days. Divers must hold PADI or NAUI Advanced Open Water credentials. Accommodation ranges from triple cabins with shared facilities to suites aboard the good ship Akademik Shokalskiy. The rate for a diving expedition...
...culture may reflect the changes in our lives, but it also plays its part in shaping them. Marketers have picked up on the fact that twixters on their personal voyages of discovery tend to buy lots of stuff along the way. "They are the optimum market to be going after for consumer electronics, Game Boys, flat-screen TVs, iPods, couture fashion, exotic vacations and so forth," says David Morrison, president of Twentysomething Inc., a marketing consultancy based in Philadelphia. "Most of their needs are taken care of by Mom and Dad, so their income is largely discretionary. [Many twentysomethings...
...newest and most surprising at-risk population, however, is the kids, a group in which hypertension, until recently, could not even be uniformly diagnosed. Optimum blood pressure changes with age and body size, and what's right for an adult is wrong for a preteen, to say nothing of a baby. A 2-year-old girl in the 50th percentile for height may have an average blood pressure of just 88/45. That same girl at age 10 should be up to 102/60, still far below the traditional adult benchmark of 120/80. The NHLBI now recommends making blood-pressure readings...
Fortunately, I don’t have mono. According to the National Sleep Foundation (NSF), most adults need between seven and nine hours of sleep and one acquires a “sleep debt” without this optimum amount of sleep. Sleep debt continually builds up every time you do not sleep enough, and can only be reversed by sleeping more than your optimum. Drowsiness is a sign that your body has accumulated sleep debt. Health experts have proven that teenagers and young adults need even more sleep than adults. According to the 2003 Gallup Youth Survey, 78 percent...
...years of cattle grazing, the banks eroded after willows were removed to make way for more hay. At the request of the landowner, Rosgen dragged in boulders and chunks of dead trees, placing them strategically to regulate stream flow. He engineered the streambed to just the right grade for optimum flow velocity, and lined it with clean gravel quarried from the property. He transplanted thousands of willow saplings to the area, reversing decades of brush-clearing efforts. The once steep banks are now grassy and gently sloping, almost parklike. Eagles soar overhead, scouting the rich fishery below...
