What's the buzz


Researchers at the University of St Andrews created the images of how three people would look in five years, 10 years and 20 years if they did less than 30 minutes of moderate physical activity five times a week.
They also created faces which had benefited from 30 minutes or more of physical exercise five, 10 and 20 years into the future.
The authors took into account the average weight gain in line with age to develop a picture of the effect no exercise had on the face.
“The aim of this study was to highlight that an active lifestyle can benefit appearance, in addition to health,” said researcher Ross Whitehead.
“By looking at the height and weight of the three volunteers, and the consequences of exercising versus not exercising for facial appearance, we were able to build an image of how they would appear in five, 10 and 20 years,” Whitehead added.
A team of 10 people used computer software developed by researchers at the university for the project. Neck and jowls are the most affected with saggy, loose skin while the forehead and eye area is fatter.

Healthy diet can ward off kidney stones
A diet designed to prevent high blood pressure reduces the risk of developing kidney stones, a new study has found.
The results suggest how low-fat dairy products and/or plants may have potent kidney stone-fighting properties.
The Dietary Approaches to Stop Hypertension (DASH) diet — which is high in fruits, vegetables, nuts and legumes, dairy products, and whole grains and is low in sweetened beverages and red and processed meats-effectively lowers blood pressure.
Research by Eric Taylor, (Brigham and Women’s Hospital, Harvard Medical School, and Maine Medical Centre) and his colleagues also now suggests that a DASH-style diet reduces one’s risk of developing kidney stones.
The investigators studied 24-hour urine samples of 3,426 individuals with and without a history of kidney stones in the Health Professionals Follow-up Study (HPFS) and the Nurses’ Health Studies (NHS) I and II. The study participants were part of a previous, larger study where Dr Taylor reported that a DASH-style diet was associated with a reduced risk of kidney stone formation. HPFS and NHS I and II are large studies of the lifestyle practices and health of both male and female health care workers.

Good memory may be key to happiness
A good working memory could be the key to a happy and successful life. Dr Tracy Alloway, University of Stirling in Scotland, and colleagues found that people with a good working memory are more likely to be optimistic and self-assured.
Those whose working memory was poor were more likely to ‘brood’ and scored higher in tests of pessimism. Working memory is the ability to remember and process information at the same time. It is employed when a person is asked to count back two digits from a number and provide the answer without hesitation.
Research suggests that individuals with good working memories tend to have better jobs and relationships. The researchers, however, wanted to see if it also had a bearing on happiness.
Tracy conducted a study of 1,200 people aged from their late teens to their sixties who were given a series of psychological tests and questionnaires.
