...Pakistan Expedition Takes Dizzying Toll In one of the deadliest episodes in mountaineering history, 11 climbers died on K2, the world's second highest peak. Falling ice severed their ropes, killing several and forcing others to either continue their descent without assistance or wait for rescue in perilous conditions. Both decisions proved fateful. With its 28,250-ft. (8,600 m) summit, steep ascent routes and rough weather, K2 is often considered the world's toughest climb...
...oldest son says, "loved the Americans," was the sole breadwinner for his large family of 13, which includes the two wives of his oldest sons and three grandchildren. The Shi'ite family lived in the predominantly Sunni neighborhood of al-Dora in southern Baghdad up until the peak of sectarian violence in late 2006.

...heart attack depends on the imbalance between increased myocardial oxygen demand (i.e., a greater need for oxygen in your heart) and decreased myocardial oxygen supply - or both. And unfortunately, some functions in the first hours of the day require more myocardial oxygen support: waking and commencing physical activities, the peak of the adrenal hormone cortisol [which boosts blood-pressure and blood-sugar levels] and a further increase in blood pressure and heart rate due to catecholamines (adrenaline and noradrenaline), which show a peak when you wake up. All those factors lead to an increase of oxygen consumption...
...these changes, however, probably are not so harmful in healthy people. But for a person with a plaque in the coronary vessel, if these changes occur at the same time and peak at the same time, the final result is a higher risk of heart attack during that specific window of morning hours...
...experimental model, in which people were instructed to stay in bed for four hours after they woke up before rising. But the same pattern simply occurred four hours after waking, because the risk is linked to our activities. We can't be afraid of the catecholamines and the peak in blood pressure in the morning. It's part of our physiology. And for healthy people, it's not a problem...
