Pacing about a supermarket doing grocery shopping would surely be healthier than sitting at home or work ordering the same items online, wouldn’t it?
Possibly not. It seems shopping online removes much of the temptation to make impulse purchases of sugary sweets, this despite various efforts by retailers to entice online shoppers into buying such treats when they reach the electronic check out.
In Britain, the country where e-commerce is most popular, about 13 percent of people do all or most of their grocery shopping online. Yet this only accounts for 5 percent of overall spending, suggesting consumers spend more when they visit a store. That is because online shoppers search for what they need, usually sticking close to their shopping lists. They don’t spontaneously buy magazines they opened while waiting to pay, or chocolate to eat on the go.

Here’s a worrying trend, children today are generally running considerably slower than their parents would have when they were the same age, and screen based entertainments and distractions appear to be the main cause:
Children around the world are less aerobically fit than their parents were as kids, a decline that researchers say could be setting them up for serious health problems once they’re grown up. Children today take 90 seconds longer to run a mile than kids did 30 years ago, according to data from 28 countries. Children’s aerobic fitness has declined by 5 percent since 1975.

You could dispense with an alarm clock, were you to go to sleep around the same time each night, every day, and wake up at the same hour the next day. Such a routine allows for the optimisation of a protein called PER, that regulates sleep, largely ensuring you wake at the same time every day.
If you follow a diligent sleep routine – waking up the same time every day – your body learns to increase your PER levels in time for your alarm. About an hour before you’re supposed to wake up, PER levels rise (along with your body temperature and blood pressure). To prepare for the stress of waking, your body releases a cocktail of stress hormones, like cortisol. Gradually, your sleep becomes lighter and lighter.

Angelo Merendino documented his wife, Jennifer’s, battle with breast cancer, through a series of photos he took from the time of diagnosis, to her death. Heart-wrenching.

What’s so bad then with a little egotism, women troubles, laziness, over action of the mind, political excitement, religious enthusiasm, superstition, greediness, grief, hard study, and business nerves (whatever that means exactly)?
It was enough, and I’m talking about just one item from the list, not necessarily more, for you to be committed to West Virginia’s Hospital for the Insane during the latter decades of the nineteenth century.

Is that a mid-life crisis you’re having, or could it all be a misconception, built up by the media, and film producers with big budgets? While mid-life angst may be a figment of our imaginations, the news is not all good, a life crisis can still come along at any age, during any decade.
At any decade in your life, our results suggest that there is a 40 to 50 percent chance of having a life crisis. There’s a slight increase with age and in general women tend to experience more than men – but that could be because they may be more open to admitting that they have had a hard time.

Next on on the agenda for search engine giant Google, yes, that’s right, you guessed it correctly, looking at ways of extending our lifespans. One way they may be able to make a contribution is by analysing the vast amounts of medical data they have access to… and whose to know what might turn up by taking such an approach?
That approach may yield unlikely conclusions. “Are people really focused on the right things? One of the things I thought was amazing is that if you solve cancer, you’d add about three years to people’s average life expectancy,” Page said. “We think of solving cancer as this huge thing that’ll totally change the world. But when you really take a step back and look at it, yeah, there are many, many tragic cases of cancer, and it’s very, very sad, but in the aggregate, it’s not as big an advance as you might think.”

Could this be the basis of a scientific explanation for so-called near death experiences, situations where people whose hearts stop beating, feel that they are drifting through what appears to be a tunnel towards a distant point of light, among other sensations?
It’s called a near-death experience, but the emphasis is on “near.” The heart stops, you feel yourself float up and out of your body. You glide toward the entrance of a tunnel, and a searing bright light envelops your field of vision. It could be the afterlife, as many people who have come close to dying have asserted. But a new study says it might well be a show created by the brain, which is still very much alive. When the heart stops, neurons in the brain appeared to communicate at an even higher level than normal, perhaps setting off the last picture show, packed with special effects.

Even though advances in medical science may allow us to live healthy, active, lives up to age 120, most US adults see living to age 90, and not much longer, as being ideal:
Given the option, most Americans would choose to live longer than the current average. Fully 69% of American adults would like to live to be 79 to 100 years old. About 14% say they would want a life span of 78 years or less, while just 9% would choose to live more than 100 years. The median ideal life span is 90 years.

It seems, for reasons that are not yet fully understood, children may be able to fend off near-sightedness if they spend more time playing outside, rather than reading, or staring at a screen of some sort, inside.
Scientists aren’t sure yet why being outside prevents kids from becoming Miss Four-Eyes early in life. There is some evidence, from studies done in lab mice, that sunlight may trigger the production of the brain chemical dopamine, which in turn prevents eyes from growing elongated. Nearsighted eyes are overly elongated. However, some conflicting studies mean that scientists can’t be sure this is what’s happening in humans.
The iPad generation isn’t going to like this news at all…
