Runners: Let Thirst Be Your Guide

Many people are drinking too much water, including sports drinks, when exercising, a practice that could put some individuals engaging in prolonged types of endurance exercise at risk of potentially lethal water intoxication, say international experts who study disorders of water metabolism. Such exercise includes marathons, triathlons, and long distance cycling.

This serious condition, known as exercise-induced hyponatremia (EAH), could be prevented if only people would respect their personal thirst "meter," or would undertake a "sweat test" to determine how much water they actually need to drink in order to replace just the body fluids lost during exercising, the researchers say.

A group of experts in this condition has issued a number of papers and recommendations, including an international consensus statement on this disorder published in the Clinical Journal of Sports Medicine in 2005. Joseph Verbalis, M.D., Professor and Interim Chair of the Department of Medicine at Georgetown University Medical Center and a member of this group, recently updated the scientific community on the causes of this disorder in the May issue of Sports Medicine.

6 myths about work

Each generation revolutionizes something. Today's younger generation is revolutionizing work. The goals people have, their values and opportunities have all changed drastically in the last 10 years. The new workplace demands new rules for success, yet people continue to get outdated advice based on persistent workplace myths.

These myths about today's workplace are adapted from my new book, Brazen Careerist: The New Rules for Success.

#1. Job hopping ruins your resume.
Job hopping is one of the best ways to sustain passion and personal growth in your career. It also helps you build a network quickly and allows you to build your skill set faster than if you worked in the same job year after year. The learning curve is always highest at the beginning.

And here's some good news for hoppers: Most people will have eight jobs between ages 18 and 32. This means most young workers are job hopping. So hiring managers have no choice but to hire job hoppers. Ride this wave and try a lot of jobs out yourself.

Disturbing! Drugging Kids: Backlash on bipolar diagnoses in children

No one has done more to convince Americans that even small children can suffer the dangerous mood swings of bipolar disorder than Dr. Joseph Biederman of Massachusetts General Hospital.

From his perch as one of the world's most influential child psychiatrists, Biederman has spread far and wide his conviction that the emotional roller coaster of bipolar disorder can start "from the moment the child opened his eyes" at birth. Psychiatrists used to regard bipolar disorder as a disease that begins in young adulthood, but now some diagnose it in children scarcely out of diapers, treating them with powerful antipsychotic medications based on Biederman's work.

"We need to treat these children. They are in a desperate state," Biederman said in an interview, producing a video clip of a tearful mother describing the way her preschool daughter assaulted her before the child began treatment for bipolar disorder. The chief of pediatric psychopharmacology at Mass. General, he compares his work to scientific break throughs of the past such as the first vaccinations against disease.

U.S. polygamist community faces rare genetic disorder

In a dusty neighbourhood under sheer sandstone cliffs studded with juniper on the Arizona-Utah border, a rare genetic disorder is spreading through polygamous families on a wave of inbreeding.

The twin border communities of Hildale, Utah, and Colorado City, Arizona, have the world's highest known prevalence of fumarase deficiency, an enzyme irregularity that causes severe mental retardation brought on by cousin marriage, doctors say.

"Arizona has about half the world's population of known fumarase deficiency patients," said Dr. Theodore Tarby, a paediatric neurologist who has treated many of the children at Arizona clinics under contracts with the state.

Fake ingredients put consumers' health at risk

American consumers are being ripped off and their health possibly put at risk because of bogus ingredients slipped into imports ranging from toothpaste to dietary supplements.

Suppliers who substitute cheaper ingredients for the real thing seldom get busted because the government and private labs review few of the products flooding in.

Brain gets a thrill from charity: study

CHICAGO - Knowing your money is going to a good cause can activate some of the same pleasure centers in your brain as food and sex, U.S. researchers said on Thursday.

People who participated in a study got a charge knowing that their money went to a charity -- even when the contribution was mandatory, like a tax. They felt even better when they voluntarily made a donation, researchers found.

Scientific research on sense of humour sheds light on psychological profiles

Is it possible to scientifically measure someone's sense of humour? Are there universally good or bad jokes that make people laugh no matter their gender, profession or cultural background? These are some of the questions answered by the doctoral thesis Sentido del Humor: Construcción de la Escala de Apreciación del Humor (Sense of humour: building of the appreciation of humour scale), carried out by Hugo Carretero Dios, researcher in the Department of Social Psychology and Methodology of Behavioural Science at the University of Granada.

This study, directed by researchers Cristino Pérez Meléndez and Gualberto Buela Casal, is the first work in Spain stemming from Psychology aimed at measuring people's sense of humour to analyse the psychological variables related to humour. Carretero Dios analysed more than 1,500 people between the ages of 18 and 80 and a similar number of men and women.

This study focused on the following types of humour: sexual humour, black humour, humour degrading to men, humour degrading to women, simple humour and complex humour. The study provided the first scientifically approved evaluation instrument in Spain to evaluate humour appreciation. Moreover, it helped to improve other instruments used in other countries.
