...Canadian researchers' findings were somewhat unexpected, given that previous studies on the issue have typically focused on aerobic exercise, which experts believe enhances cognitive function by promoting blood flow to the brain. Liu-Ambrose says her team speculated that anaerobic weight training would have a similar effect for other reasons. First, a resistance-training regimen requires a considerable amount of learning, especially for elderly people who may not be accustomed to the equipment. To learn how to use dumbbells, a leg press or a latissimus pull-down machine correctly, for example, the volunteers were required to focus on the task...
...women also had to remember their weight settings and adjustments to the seats and keep track of the number of repetitions they completed, says Liu-Ambrose. "There is a lot more learning involved that may not occur if you take up a walking program," she says, noting that it took the volunteers a good two months to get comfortable with the equipment and the training regimen...
...addition, Liu-Ambrose says, other studies have found that people who weight-train show an increase in blood levels of a growth factor that is important for maintaining skeletal mass. This factor, it turns out, also promotes nerve growth, which could be another way that resistance training boosts mental function. (See the best pictures...
...group found that this benefit occurred across all weight divisions, meaning that even among those who were overweight or obese, women who exercised improved their odds of aging without chronic disease. The effects may apply across different age groups as well; the women were at least 60 years old by the time they enrolled in the study, and while Sun was not able to determine how long they had been exercising prior to that, the results suggest that the health benefits are not limited to the young.

...Take Lebanon's Hizballah, an organization whose early days were steeped in terrorism: it made a point of never botching an attack, bombing or kidnapping. So when Hizballah said it was not going to stop until it drove the West out of Lebanon, that threat carried a lot of weight. And the credibility of Hizballah's threat convinced U.S. President Ronald Reagan that Lebanon was lost, which prompted him to withdraw the Marines who were stationed there. In the Middle East, this is not stale history; and it's a history that bin Laden certainly hasn't forgotten. (See pictures...
