Laura Geraghty was shocked 21 times before she came back from cardiac arrest with tales of the afterlife.

Our special this weekend, “Another Day: Cheating Death,” includes the story of Laura Geraghty, a school bus driver in Massachusetts who survived a cardiac arrest that left her without a heartbeat for 57 minutes. While the medical aspect is astounding, just as interesting is the story Geraghty told when she was revived.

She’d floated out of her body, and found herself in a world of incredibly bright light – heaven, she says. While there she saw her son, daughter, granddaughter and even her ex-husband – who wouldn’t take her hand when she reached out to him. Eventually she came back to the real world.

Many cultures and religions describe a vivid world on the border of life and death, but the classic modern near-death experience, or NDE, was described by Dr. Raymond Moody in his 1966 book, “Life After Life.” While not every NDE includes the same features, among the most common – according to Moody – are bright lights, a tunnel, a sense of being out of the body and an intense feeling of peace and calm.

Most people who return from the verge of death with memories like this say it’s a life-changing experience. Many view it as direct proof of an afterlife – that the place they “visit” is the world we all will see after we die. But increasingly, near-death experience (a term coined by Moody) is being studied from the perspective of science.

Dr. Kevin Nelson, a neurologist at the University of Kentucky, believes an NDE is caused by REM activity, the same type of brain activity that’s linked to dreaming. REM activity, says Nelson, can be triggered by intense stress or even lack of oxygen. In fact, he says many people experience an out-of-body experience during fainting episodes, or if they momentarily lose blood flow to the brain – as in a massive head rush.

Mary Peterson's daughters, 3 and 1, will not be getting the new vaccine, she said.

Mary Peterson of Des Moines, Washington, doesn't believe the vaccine for the novel H1N1 flu has been studied enough to get it for herself and her daughters, who are 1 and 3 years old.

"I wrestled with it," she said. "I think the side of caution in this case is just waiting until we have more information."

Peterson is one of many parents who are discussing - whether in real life or on Twitter - their skepticism of the vaccine. The vaccine is being distributed as an intranasal spray this week, and will arrive next week in injection form, said Dr. Thomas Frieden, director of the Centers for Disease Control and Prevention, earlier this week.

The CDC and other public health authorities say the new vaccine is safe, and are encouraging everyone to get it, especially those in high risk groups. But experts acknowledge that many people struggle with the decision.

"I bet half the people in the country have concerns," Dr. Mehmet Oz, host of the "Dr. Oz Show" and professor of surgery at Columbia University, told CNN's Anderson Cooper earlier this week.

Ever wonder why your physician only spends 5-10 rushed minutes with you during your office visit? You may think it’s because there are simply too many patients vying for her time, but that’s not the real reason. The root cause is that health insurance companies are stealing time from your visit by requiring excessive documentation from your doctor. She can’t give you the time you need, because doing so would put her out of business.

In a special report on the administrative burden of healthcare, MedPage Today revealed that PCPs spend about one third of their income on documentation required by health insurers. Because they run a business with thin margins, they must increase the volume of patients they treat in order to cover the salaries of the staff required to manage this “paper weight.”

About 49% of all physicians have said that they are considering retiring or quitting medicine in the next two years (the rate is lower for specialists), largely because of increasing documentation requirements and decreasing reimbursement.

On a cold morning in February, 10 days after undergoing in vitro fertilization, Carolyn Savage lay in bed at her Ohio home waiting for the results of her pregnancy test.

Time was moving slowly. It was getting late and the call from the fertility clinic should have come by lunchtime.

"We were waiting and waiting and the call seemed like it would never come," Savage said.

Finally, around 4 p.m., Carolyn's husband, Sean, got the call at work.

"The doctor told me in one sentence, 'Carolyn is pregnant, but we transferred the wrong embryos,'" he said. "I didn't even know that could physically happen. It was a total shock, totally beyond the realm of possibility."

In a tragic mix-up, the Savages say the fertility clinic where Carolyn underwent in vitro fertilization implanted another couple's embryos into Carolyn's uterus.

The H1N1 flu virus could cause up to 90,000 U.S. deaths, mainly among children and young adults, if it resurges this fall as expected, according to a report released Monday by a presidential advisory panel.

The H1N1 virus, commonly known as swine flu virus, could infect between 30 percent and 50 percent of the American population during the fall and winter and lead to as many as 1.8 million U.S. hospital admissions, the President's Council of Advisors on Science and Technology reported.

The report says 30,000 to 90,000 deaths are projected as part of a "plausible scenario" involving large outbreaks at schools, inadequate antiviral supplies and the virus peaking before vaccinations have time to be effective.

Do you have questions about these numbers? Let us know! Dr. Sanjay Gupta will be on 360° to answer them tonight.

When President Obama recently cited the number of Americans without health insurance, he declared that, "We are not a nation that accepts nearly 46 million uninsured men, women, and children."

Uninsured patients often delay preventive care, waiting to seek medical attention only when their conditions worsen. This leads to more intensive treatment, often in the emergency department or hospital where costs run the highest.

Universal health coverage is therefore a sensible goal, and the reforms being considered all make considerable effort to provide everyone with affordable health care.

But expanding coverage cannot succeed as long as there remains a shortage of primary care clinicians.

After all, what good is having health insurance if you can't find a doctor to see you?

Digitizing health records. A good idea say most experts, but it will take a feat of policy, technology and education to ensure your records don't get into the wrong hands.

It all starts with one basic question: Who actually owns your health records?

"Right now, hospitals assume the liability, but the model has to shift to one where the patient controls the data and whether it is put online," said Dr. David Brailer, chairman of Health Evolution Partners and former health tech czar under President Bush. "The people who hold your data control your data."
