Clinicians and scientists have known for a long time of the many health benefits obtained by regularly performing physical activity (PA). Studies by Morris and colleagues12 50 to 60 years ago showed that male workers in occupations requiring them to be physically active had significantly lower rates of coronary heart disease in middle age than those with sedentary occupations. The research evidence base grew substantially over the years, leading to 2 major public health statements promoting the importance of PA for health and the American Heart Association adding physical inactivity to the major risk factor list in the 1990s.35In 2008, the first federal Physical Activity Guidelines were issued based on evidence that engaging in 150 minutes per week of moderate‐intensity PA or 75 minutes per week of vigorous‐intensity PA would result in substantial health benefits.6 This recommendation implies that the total volume of PA, regardless of whether it is performed at moderate or vigorous intensity, is the key for stimulating health benefits. The study by Shiroma and colleagues7 in this issue of JAHA used an epidemiological approach to evaluate whether there were differences in mortality rates based on the proportion of total PA volume obtained with moderate or vigorous intensity. This experienced author group used data provided by 2 major cohorts, the Harvard Alumni Health Study and the Women's Health Study, each of which has brought us a wealth of evidence of factors associated with health, including PA. They report that the most active men and women had mortality rates 36% to 55% lower than those who were least active and that there was a modest (4% to 10%) additional benefit for men if a greater proportion of the total PA volume was of vigorous intensity./.../


Google Wants Inbox to Be Your Email System for the Next Decade

A promotional video for Inbox.

Google’s signature email program first hit the Web in 2004. In its earliest days, it was a godsend to everyone who battled against a daily rush of messages.
Two years ago, a team of engineers and designers on Google’s Gmail team decided that Gmail wasn’t cutting it.

Harassement Online

40 Percent of US Adults Harassed Online

The conversation about bullying often revolves around youngsters, but they are not the only victims. Data show that some 40 percent of US adults face harassment online in the form of name-calling, intentional embarrassment, threats, sexual harassment, and stalking. Of adults targeted in this manner, young adults are the most frequently victimized, with 65 percent reporting being subjected to such harassment. Gender also appears to influence the type of online harassment one faces, with men more likely to experience name-calling and women more likely to be targeted for sexual harassment and stalking.

Mental illness and society

A better response to Ottawa shooting

"Too often those with mental illness and those who suffer from terrible addictions are ignored and left to their own devices in a society that has not provided the necessary care," said Prime Minister Stephen Harper in the House of Commons. - See more at:

Personal x Digital Spaces

Ask Ray | US Supreme Court acknowledges that personal space has merged with the digital world

June 28, 2014 by Ray Kurzweil
Dear readers,
My friend — of 50 years! — Mark Bergmann, brought this recent quote from US Supreme Court Chief Justice John Roberts to my attention:
“Modern cell phones are such a pervasive and insistent part of daily life that the proverbial visitor from Mars might conclude they were an important feature of human anatomy,” said Roberts, commenting in the recent Supreme Court ruling on cell phones warrants.… read more

Wild ride ahead: glimpse at humanity’s long range future

July 23, 2014 by Richard (Dick) Pelletier
Imagine if you could take an exotic vacation billions of light years from Earth, peek in on the dinosaurs’ first-hand, or jump into a parallel universe where another you is living a more exciting life than yours — and you could swap places if you like.
For years, scientists have bandied about radical ideas that future humans will one day harness wormholes to zip across the universe at faster-than-light… read more

‘Hidden brain signatures’ of consciousness in vegetative state patients discovered

October 21, 2014
Scientists in Cambridge, England have found hidden signatures in the brains of people in a vegetative state that point to networks that could support consciousness — even when a patient appears to be unconscious and unresponsive. The study could help doctors identify patients who are aware despite being unable to communicate.
Although unable to move and respond, some patients in a vegetative state are able to carry out tasks such… read more

Universe timeline

 The incredible unlikelihood of being

July 24, 2014
Hello Ray,
The universe existed several billion years before humans were conscious, and will exist several billion years after we are conscious.
So, it is statistically improbable for the chronological timeline of the universe to be located at this precise moment, when we are conscious, that is, an 80 year lifespan within some 30 billion years.
Are you aware of any theories, besides survivorship bias from statistics, that… read more

Being Mortal

Being Mortal: Medicine and What Matters in the End
Atul Gawande
Metropolitan Books/Henry Holt and Company2014304
US$26·00 ISBN-9780805095159
Ignoring W C Fields' famous advice never to work with children or animals, Dr Bill Thomas introduced both to the Chase Memorial Nursing Home in New York during the 1980s: two dogs, four cats, 100 parakeets, a colony of rabbits, a flock of chickens, and an on-site childcare facility for staff, to be precise. The initial effect was chaos (especially since the birds arrived uncaged), but over the next 2 years the number of prescriptions per resident dropped in half and even the mortality rate declined. In his new book Being Mortal: Medicine and What Matters in the End, surgeon and New Yorker staff writer Atul Gawande highlights this and other examples of the transformative power of thinking differently about medical care at the end of life.
In fact, if there is a recurring theme in Gawande's elegant and impactful writing it is his showcasing simple but effective ways of making people's lives—and their doctors' impact on them—better. (The title, in fact, of his second book.) In Being Mortal, he continues this tradition as he explores our society's medicalisation of the final chapter of our lives./.../

All-Purpose Antidepressants

The Rise of All-Purpose Antidepressants

Doctors are increasingly prescribing SSRIs to treat more than just depression

Antidepressant use among Americans is skyrocketing. Adults in the U.S. consumed four times more antidepressants in the late 2000s than they did in the early 1990s. As the third most frequently taken medication in the U.S., researchers estimate that 8 to 10 percent of the population is taking an antidepressant. But this spike does not necessarily signify a depression epidemic. Through the early 2000s pharmaceutical companies were aggressively testing selective serotonin reuptake inhibitors (SSRIs), the dominant class of depression drug, for a variety of disorders—the timeline below shows the rapid expansion of FDA-approved uses.
As the drugs' patents expired, companies stopped funding studies for official approval. Yet doctors have continued to prescribe them for more ailments. One motivating factor is that SSRIs are a fairly safe option for altering brain chemistry. Because we know so little about mental illness, many clinicians reason, we might as well try the pills already on the shelf./.../
