As pot belly expands, sudden cardiac death risk shrinks
Being skinny confers no advantage when it comes to the risk of dying suddenly from cardiac causes, say researchers. In fact, boffins at the University of Rochester Medical Center found that non-obese heart failure patients - including overweight, normal and underweight patients - had a 76 per cent increase in risk of sudden cardiac death compared to obese heart failure patients. Normal and underweight patients showed a startling 99 per cent increase in risk for sudden cardiac death compared to obese patients.
Now, it's still true that a beer belly, love handles, and other extra layers of fat boost your risk of developing diabetes, clogged arteries and high blood pressure. And if you're very fat, you're more likely to develop an enlarged, weakened heart that struggles to pump blood efficiently -- the physical condition known as heart failure. But, paradoxically, in this study of more than 1,200 heart failure patients, that excess weight seemed protective against sudden death.
The researchers can't explain why at this point. But they know it's not that the skinny people in their study were skinny because they were extra sick and so would be more likely to drop dead, in any event. And even normal-weight people in the study had a higher risk of sudden death than obese patients.
"Obese patients are hard on their bodies; many don't eat right, don't exercise, and many smoke," says Eric Hansen, a medical student at the University of Rochester, and co-author of the study. "If their bodies are surviving this bad treatment, then perhaps they are better equipped, from a genetic standpoint, to live with heart failure."

As pot belly expands, sudden cardiac death risk shrinks

Let’s say it’s 6.15pm and your driving home (alone of course) after an unusually hard day on the Job. You’re really tired and frustrated.
Your are Really Stressed and Upset
Suddenly you start Experiencing Severe Pain in your CHEST that starts to radiate out in to your arm and up in to your Jaw.
You are only Five miles from the Hospital nearest home.
Unfortunately you don’t know if you’ll be able to make it that far.
WHAT TO DO?
You have been trained in CPR; But the Guy that Conducted the Course did not tell you how to perform it on yourself.
HOW TO SURVIVE A HEART ATTACK WHEN ALONE?
Since many people are alone when they suffer a Heart Attack, without help, the person whose heart is Beating Improperly and who begins to feel faint, has only about 10 seconds left Before Losing Conscious
1) Do not panic, but start coughing repeatedly and very vigorously.
2) A Deep Breath should be taken before each cough the cough must be deep and prolonged, as when producing Sputum from Deep inside the Chest
3) A Breath and a cough must be Repeated about every two seconds without let-up until help arrives, or until the heart is felt to Beating Normally Again.
4) Deep Breath get Oxygen into the lungs and coughing movement squeeze the heart and deep the Blood Circulating. The Squeezing pressure on the Heart also helps it regain Normal rhythm.
In this Way, HEART ATTACK Victims can get to a Hospital.

This Nanotechnology Center was being built in the spring of 1990, as Eric Drexler was midway through a hectic eight-day trip, giving talks on nanotechnology to researchers and seeing dozens of university and consortium research laboratories. A Japanese research society had sponsored the trip, and the Ministry of International Trade and Industry MITI) had organized a symposium around the visit—a symposium on molecular machines and nanotechnology. Japanese research was forging ahead, aiming to develop "new modes of science and technology in harmony with nature and human society," a new technology for the twenty-first century
There is a view of the future that doesn't fit with the view in the newspapers. Think of it as an alternative, a turn in the road of future history that leads to a different world. In that world, cancer follows polio, petroleum follows whale oil, and industrial technology follows chipped flint—all healed or replaced. Old problems vanish, new problems appear: down the road are many alternative worlds, some fit to live in, some not. We aim to survey this road and the alternatives, because to arrive at a world fit to live in, we will all need a better view of the open paths.
A Sketch of Technologies
Molecular nanotechnology: Thorough, inexpensive control of the structure of matter based on molecule-by-molecule control of products and byproducts; the products and processes of molecular manufacturing.
Technology-as-we-know-it is a product of industry, of manufacturing and chemical engineering. Industry-as-we-know-it takes things from nature—ore from mountains, trees from forests—and coerces them into forms that someone considers useful. Trees become lumber, then houses. Mountains become rubble, then molten iron, then steel, then cars. Sand becomes a purified gas, then silicon, then chips. And so it goes. Each process is crude, based on cutting, stirring, baking, spraying, etching, grinding, and the like.
Trees, though, are not crude: To make wood and leaves, they neither cut, grind, stir, bake, spray, etch, nor grind. Instead, they gather solar energy using molecular electronic devices, the photosynthetic reaction centers of chloroplasts. They use that energy to drive molecular machines—active devices with moving parts of precise, molecular structure—which process carbon dioxide and water into oxygen and molecular building blocks. They use other molecular machines to join these molecular building blocks to form roots, trunks, branches, twigs, solar collectors, and more molecular machinery. Every tree makes leaves, and each leaf is more sophisticated than a spacecraft, more finely patterned than the latest chip from Silicon Valley. They do all this without noise, heat, toxic fumes, or human labor, and they consume pollutants as they go. Viewed this way, trees are high technology. Chips and rockets aren't.
Trees give a hint of what molecular nanotechnology will be like, but nanotechnology won't be biotechnology because it won't rely on altering life. Biotechnology is a further stage in the domestication of living things. Like selective breeding, it reshapes the genetic heritage of a species to produce varieties more useful to people. Unlike selective breeding, it inserts new genes. Like biotechnology—or ordinary trees—molecular nanotechnology will use molecular machinery, but unlike biotechnology, it will not rely on genetic meddling. It will be not an extension of biotechnology, but an alternative or a replacement.
A Sketch of Consequences
Here are a few of today's common assumptions, some so familiar that they are seldom stated:
• Industrial development is the only alternative to poverty.
• Many people must work in factories.
• Greater wealth means greater resource consumption.
• Logging, mining, and fossil-fuel burning must continue.
• Manufacturing means polluting.
• Third World development would doom the environment

Hi EveryBody Sounds Interesting Read it. Share the knowledge to others,
A 67-million-year-old fossil of a gigantic snake found coiled around a dinosaur egg in the village of Dholi Dungri in Virpur taluka in Gujarat’s Kheda district has helped an international paleontological team led by the University of Michigan’s Jeff Wilson and Geological Survey of India’s Dhananjay Mohabey to confirm this unusual feeding behaviour.
The snake did not eat fully-grown sauropods, it preyed on dinosaurs just as they were hatching from eggs. It coiled around the prey to kill and swallow it.
“It’s a chance to understand the biology and early anatomy,” said Jeffrey A. Wilson, the paper’s lead author and a paleontologist at the University of Michigan. “The really important thing is that it’s actually caught in the fossil record showing what its doing.”
The study is significant as the nearly complete remains of the snake — preserved in a nest of a sauropod along with a half-metre-long dinosaur hatchling lying next to the snake and two unbroken eggs — is unequivocal evidence of its eating behavior.
One of the most important features that enable macrostomatans to prey on animals bigger than a deer is their wide gap. Fully grown pythons have excellent jaw adaptations and elongated skulls that give them a gape as wide as 60 cm.
