Height of jealousy

Shorter men are more likely to be jealous husbands and boyfriends than their taller counterparts, suggests a fascinating research, which may finally have proof for the controversial ‘Napoleon complex’.
The studies, reported in the New Scientist journal, believes it reflects insecurities among men who are not society’s “ideal” height. The much-talked about ‘short man syndrome’ is a phenomenon where short men compensate for their lack of height by inculcating aggressive tendencies, often associated with Napoleon, Mussolini, Hitler and Attila the Hun.
In the study carried out by the University of Groningen in the Netherlands, researchers asked men and women how jealous they were in their current relationships.
In another similar study, involving 119 male and 230 female students, the participants were quizzed on their reaction if they saw their girlfriend, or boyfriend, flirting with a stranger. The findings suggested that shorter men were far more likely to say they were jealous than taller ones.
“Taller men tended to be less jealous, and the tallest men were the least jealous,” the Daily Mail of Britain quoted the researchers, led by Dr Abraham Buunk, as saying. Among the women, average sized females were the least jealous- while tall and short women were the most.
Repeated studies have shown that women rate taller men as more attractive and powerful than shorter ones, while men prefer “average” women, usually who are a couple of inches shorter than them in height.

WASHINGTON: If you have been contemplating going back to school to get a degree, this might convince you: a study by the Harvard School of Medicine has shown people with a better education live longer.
“Between the 1980s and 2000, life expectancy increases occurred nearly exclusively among high-education groups,” the study said.
While life expectancy for people with a high school degree or less did not change between 1990 and 2000, the better-educated gained more than 1.5 years over the same period, the study showed. “A 25-year-old with a high school degree in 1990 could expect to live another 50 years, or for about 75 years,” lead author Ellen Meara said.
“Looking at a similarly educated 25-year-old in 2000, you have the same expected life span,” said Meara, assistant professor of healthcare policy at Harvard Medical School.
“For the better educated, you have an expected life span of 80 years in 1990, but it’s 81.6 by the year 2000. So it’s quite a big gain.” The reasons for such longevity appear to be that more educated people have better access to both information about disease and medical advances.
“Quite literally, why are the better educated living longer? They’re less likely to die of diseases,” said Meara. Life expectancy grew across the board for all races and genders between 1990 and 2000, showed the study, which looked only at non-Hispanic blacks and whites to “limit the impact of immigration on estimates.”
Screen kidney, be safe

NEW DELHI: On World Kidney Day on Thursday, nephrologists want to raise awareness about Chronic Kidney Disease (CKD), incidents of which are increasing at an alarming rate.
If you have diabetes or high blood pressure, then you are at a risk of developing CKD. Unfortunately, by the time a person is diagnosed with CKD, nearly 50% of his kidneys are damaged. This happens because the blood creatinine levels, which are the indicators for kidney disease, don’t rise till 50% of the kidney functioning is affected.
During routine check-up, most doctors don’t study the creatinine levels of the patient if it is in the normal range. “But normal creatinine level doesn’t mean that the patient’s kidneys, especially those who have diabetes or high BP, are functioning properly. There is a need to study the creatinine levels seriously with respect to the patient’s weight, age, sex and history of diseases,” said Dr Vijay Kher, director, nephrology and kidney transplant unit, Fortis Healthcare.
Routine check-up doesn’t involve creatinine level assessment. “It is only in cases which have history of high BP or diabetes or any other ailment or they present with CKD symptoms, then we screen for CKD,” said Dr Mukesh Mehra, HoD, internal medicines, Max Healthcare.
Creatinine is freely filtered by the glomerular capillaries, inside the nephrons, and a small amount is also secreted in our body. But when these nephrons get damaged either due to high BP or diabetes, then the Glomerular Filtration Rate (GFR) also decreases. As a result of this, the creatinine level increases in a patient’s body.
“Unfortunately, the creatinine levels increase only after the GFR is affected nearly 50%. This means when the kidneys are nearly 50% damaged, it is then a patient is diagnosed with CKD. But by then it is too late,” said Dr Sanjeev Bagai, director and paediatric nephrologist, Rockland Hospital.
The prevalence of CKD is “one in 10 people in different stages of the disease. This varies from mild to severe form called, the End Stage Kidney Disease (ESKD),” said Dr S K Agarwal, additional professor, department of nephrology, AIIMS.
He added, “The reason for this in most cases is lifestyle related. High BP and diabetes are very common today. Most of the CKD patients have either of the two, especially in the urban population.
“If CKD is diagnosed in the early stages, it can be managed well and need for dialysis and a transplant in a patient can be delayed. A creatinine clearance test along with patient’s medical history can help a physician diagnose whether he/she is a case of CKD or not,” said Dr Kher.
CKD can happen in children too and can affect newborns as well. “A woman’s nutrition during pregnancy can affect the baby. It has been seen that newborns with low birth weight stand a chance of developing kidney diseases and also high BP when they grow up,” said Dr Agarwal. The common symptoms of CKD are: high HP, diabetes, low haamoglobin, difficulty in passing urine or blood in urine and swelling in body parts.
“If anybody has all these symptoms, then a routine ultrasound of the kidneys is a must. With this we can pick up kidney problems in the early stages,” said Dr Bagai.
Though there are no screening programme for CKD by the government, doctors say a screening test would not cost more than Rs 100 when compared with the cost of treatment of renal failure cases. So next time you go for a routine check-up, do ask the doctor for a CKD screening test, especially those who have above-mentioned symptoms and are BP or diabetes patients.
Morning sex can keep you healthy

LONDON: A steamy sex session in the morning can keep you in good health, say British researchers.
According to a research from Queen’s University in Belfast, a good morning session at least three times a week, decreases the risk of heart attack or stroke by half and a regular session improves circulation, thereby reducing blood pressure.
According to a study in New Scientist, a steamy session twice a week enhances IgA, an antibody that provides protection against microbes that multiply in body secretions, reports the ‘Sun’. Morning sex also helps in alleviating arthritis and migraine. It burns around 300 calories an hour that simultaneously diminishes the risk of developing diabetes.
Moreover, an American study involving 300 sexually active women whose partners did not use condoms revealed that they were less prone to depression.
Sex increases the production of testosterone that provides stronger bones and muscles thus helping to stave off osteoporosis.
A good morning session can make the hair shine and skin glow by raising the output of oestrogen and other hormones which are associated with it.
According to Yale School of Medicine researchers, having morning sex can aid in averting endometriosis, a condition where the tissue that normally lines the uterus, grows in other parts of the pelvis.

Ant world is rife with royal corruption

WASHINGTON: They may be held-up as the ideals of social co-operation but ants can be as sneaky as humans and their colonies are rife with cheating and corruption–with the royal line being the worst offenders, say scientists from the Universities of Leeds and Copenhagen.
Ants have always been thought to work together for the benefit of the colony rather than for individual gain, but Dr Bill Hughes from Leeds’ Faculty of Biological Sciences has found evidence to shatter this illusion.
With Professor Jacobus Boomsma from the University of Copenhagen, Hughes discovered that certain ants are able to cheat the system, ensuring their offspring become reproductive queens rather than sterile workers.
“The accepted theory was that queens were produced solely by nurture: certain larvae were fed certain foods to prompt their development into queens and all larvae could have that opportunity,” said Hughes.
“But we carried out DNA fingerprinting on five colonies of leaf-cutting ants and discovered that the offspring of some fathers are more likely to become queens than others. These ants have a ‘royal’ gene or genes, giving them an unfair advantage and enabling them to cheat many of their altruistic sisters out of their chance to become a queen themselves,” he added.
But what intrigued the scientists was that these ‘royal’ genetic lines were always rare in each colony.
Hughes said: “The most likely explanation has to be that the ants are deliberately taking steps to avoid detection. If there were too many of one genetic line developing into queens in a single colony, the other ants would notice and might take action against them. So we think the males with these royal genes have evolved to somehow spread their offspring around more colonies and so escape detection. The rarity of the royal lines is actually an evolutionary strategy by the cheats to escape suppression by the altruistic masses that they exploit.”
However, the scientists’ discovery does prove that, although social insect colonies are often cited as proof that societies can be based on egalitarianism and cooperation, they are not quite as utopian as they appear.
“When studying social insects like ants and bees, it’s often the cooperative aspect of their society that first stands out,” said Hughes.
“However, when you look more deeply, you can see there is conflict and cheating – and obviously human society is also a prime example of this. It was thought that ants were an exception, but our genetic analysis has shown that their society is also rife with corruption – and royal corruption at that!” added Hughes.
The study is published in the Proceedings of the National Academy of Sciences of the USA
