Drinking water with a relatively high concentration of magnesium protects against hip fractures, according to results of a study by the Norwegian Institute of Public Health.  They found that magnesium protects against hip fracture for both men and women. They found no independent protective effect of calcium.  

The study notes that there are considerable variations in the quality of drinking water in Norway. The researchers studied variations in magnesium and calcium levels in drinking water between different areas, as these are assumed to have a role in the development of bone strength.

They wanted to examine whether there was a correlation between magnesium and calcium concentrations in drinking water and the incidence of hip fracture. 

Tampa, FL (Feb. 6, 2014) – Declines in the underlying brain skills needed to think, remember and learn are normal in aging. In fact, this cognitive decline is a fact of life for most older Americans.

Therapies to improve the cognitive health of older adults are critically important for lessening declines in mental performance as people age. While physical activity and cognitive training are among the efforts aimed at preventing or delaying cognitive decline, dietary modifications and supplements have recently generated considerable interest.

Now a University of South Florida (USF) study reports that a formula of nutrients high in antioxidants and other natural components helped boost the speed at which the brains of older adults processed information.

What shapes a man’s life?

To begin: Mom, dad, little Jenny Harrison in the 3rd grade, adolescence, acne, heartache, and the jockstrap.

And then there comes the real trauma, age 60 or so: loss of gluteofemoral adipose tissue.

As in:

Sagging of the butt

Collapse of the “gluteo-pecs”

and even...

Disappearance of the “back package.”

You know what I’m talking about. It’s that age-related reworking of your once-marvelous physique, when we replace pecs with moobs, 6-pac abs with a two-liter jug and slim leg Levy’s for old time beltless-wear.

Here is how I found out about it:

Tailor: “What is going on back here? Looks like...diapers. Pampers!”

Me: “What do you mean?”

With any pesticide, over-use can have harmful effects on the environment. 

DDT has not been used in America for over four decades but Rutgers scholars say that exposure to DDT may also increase the risk and severity of Alzheimer's disease in some people, particularly those over the age of 60. 

World War II had consequences for continental Europeans. Living in a war-torn country increased the likelihood of a number of physical and mental problems later in life, according to a paper by economists. 

When you think of treating urinary incontinence in senior women, what is the first thing that comes to mind?

Probably not dancing. But maybe it will work, and it sounds like fun. 

For a study of potential benefits of dancing (and virtual reality), researchers added a series of dance exercises via a video game console to a physiotherapy program for pelvic floor muscles. The results of the small study (24 participants) was a greater decrease in daily urine leakage than for the usual program (so, an improvement in effectiveness) as well as no dropouts from the program and a higher weekly participation rate (an increase in compliance). 

Medical researchers have found a way to reverse a cause of aging in animals - and it doesn't involve starvation. 

The work relates to mitochondria, which are our cells' battery packs and give energy to carry out key biological functions, and a series of molecular eventsthat  enable communication inside cells between the mitochondria and the nucleus. As communication breaks down, aging accelerates. 

Ignoring meaningless platitudes like 'age is all in your mind', age is more than a number of years. 'You are as young as you feel' may be more apt because factors such as health, cognitive function and disability rates are important ways to measure age in all its dimensions.

International Institute for Applied Systems Analysis
population researchers Warren Sanderson and Sergei Scherbov seek to reorient the way demographers study population aging, providing a new toolbox of methodologies for demographers to better understand the impacts of an aging population on society, by measuring based instead on characteristics of people that change with age, including life expectancy, health, cognitive function, and other measures. 

The concept of permanent neurological injury is so 20th century.

Instead, there has been gradual recognition of the brain's potential for long-term regeneration and reorganization and so rehabilitations strategies are undergoing radical changes. The potential for five new translational interventions was examined in an recent Neurology Clinical Practice article.

It's said that being an astronaut is no longer a bold endeavor. The job works program nature of NASA and a no-risk approach to missions by government has meant a drop in prestige among the public. It used to be risky and that captured the public's imagination.

Some day, if presidents stop canceling the space programs of their predecessors, man may leave orbit again, and astronauts will gain some new respect, because even if the mission is successful astronauts are paying a price - their cells are aging faster in microgravity.
