Thursday: Health Points

"I never would have thought that we would be seeing these effects into the later 20s," said study co-author Kim Dietrich, a professor of environmental health at the University of Cincinnati. "I'm actually quite astounded and quite worried about this. Although lead levels have been going down in this country, a large proportion of the population now in their 20s and 30s had blood levels in this neurotoxic range."

Childhood lead exposure has been linked with anti-social behavior, lower IQ, attention deficits, hyperactivity and weak executive control functions, all of which are risk factors for future delinquent behavior (attention-deficit hyperactivity disorder, in particular, is a risk factor for adult criminal behavior). Studies have also related sales of leaded gasoline or high atmospheric lead levels with criminal behavior.
Peak Corn: Blame Earl Butz. Richard Nixon and Gerald Ford's Secretary of Agriculture brought in the Farm Bill that dramatically increased the amount of corn produced in America. He encouraged farmers to "get big or get out," and to plant crops like corn "from fence row to fence row." Further billions in subsidies to farmers encouraged production, and soon America was awash in cheap grain, and with it cheap meat.


Peak Dirt: Really, Peak Dirt- the world is losing soil 10 to 20 times faster than it is replenishing it. Drake Bennett in the Boston Globe tells us that dirt is complicated stuff, made from sand or silt, then years of plants adding nutrition, bugs and worms adding their excrement, dying and rotting.
California Water Service Company reports high levels of mercury in water making it useless for drinking. Every attempts of purifying the water, such as boiling it, are useless, because the pollution level is high.


Mercury is much more dangerous when drinking than when breathing. However, boiling the water leads to mercury release into the air, so the pollution and health risk still exists.

California Water Service Company is now notifying residents about health concerns. Sheriff's Office itself is investigating the case to find out the reasons of why mercury level is so high.
Get enough sleep: Most of us know that money can't buy happiness, but who knew that a good night's sleep just might? That's a key finding of that University of Michigan study. "Making $60,000 more in annual income has less of an effect on your daily happiness than getting one extra hour of sleep a night," says study author Norbert Schwarz, Ph.D., a professor of psychology.


Take the long view: Having a sense of perspective will also improve your attitude. "It gives you more patience, and it certainly awakens you to the preciousness of the moment, which is fleeting," says M.J. Ryan, author of The Happiness Makeover. She remembers the times when her daughter wanted to sit on her lap and watch a video. "Yes, I had other things to do. But I said to myself, 'How long will this last?' I'm grateful for that time with her."
The germ, resistant to some antibiotics, has become a regular menace in hospitals and nursing homes. The study found it played a role in nearly 300,000 hospitalizations in 2005, more than double the number in 2000.


The infection, Clostridium difficile, is found in the colon and can cause diarrhea and a more serious intestinal condition known as colitis. It is spread by spores in feces. But the spores are difficult to kill with most conventional household cleaners or antibacterial soap.

C-diff, as it's known, has grown resistant to certain antibiotics that work against other colon bacteria. The result: When patients take those antibiotics, competing bacteria die off and C-diff explodes.
Dr. Monique M. B. Breteler told Reuters Health that her group had previously found that men, but not women, with a silent heart attack are more likely to have a stroke than men who had a recognized heart attack or those who had not had any heart attack.


To examine whether this might also be the case for dementia and so-called cerebral small vessel disease, Breteler of Erasmus University, Rotterdam, and her colleagues examined data for more than 6300 participants in a population-based study.

At the start of the study, from 1990 to 1993, the subjects were classified as having a recognized heart attack, not having a heart attack, or having had an unrecognized heart attack based on EKG tracings. They were followed for the occurrence of dementia, of which there were 613 cases by 2005.
The Food and Drug Administration gained new powers in March to require distribution limits or other restrictions on the sale of new medicines.


"That's taking a considerable amount of time more for every application. That will go away in time," Janet Woodcock, director of the FDA's Center for Drug Evaluation and Research, said in an interview with Reuters.

At present, the process is adding days or weeks to reviews of drugs that need the additional safety measures, she said.

Woodcock has worked at the FDA for more than two decades. In March, she returned to a previous post running the agency's drugs division after taking other leadership responsibilities.
Social psychologists have already shown that thoughts about death can spur buying behaviour. For example, in the months following 9/11 shops in the US noted a spike in purchases of luxury products, canned goods and sweets.


To better understand the link between thoughts of mortality and the urge to consume, Naomi Mandel at Arizona State University, Tempe, and Dirk Smeesters at Erasmus University in Rotterdam, the Netherlands, asked 746 students to write essays on one of two topics: their death or a visit to the dentist. Each participant also completed a questionnaire designed to evaluate their level of self-esteem.

They found that subjects with low self-esteem who wrote about death ate more cookies, when given the opportunity, and bought more items from a hypothetical shopping list compared to those who wrote about the dentist. In people with high self-esteem, thoughts of death had little effect.
