A study led by Professor Mark Weiser of Tel Aviv University and the Sheba Medical Center at Tel Hashomer Hospital has determined that young men who smoke are likely to have lower IQs than their non-smoking peers (同龄人). Tracking 18-to 21-year-old men enlisted in the Israeli army in the largest ever study of its kind, he has been able to demonstrate an important connection between the number of cigarettes young males smoke and their IQ.
The average IQ for a non-smoker was about 101, while the smokers’ average was more than seven IQ points lower, at about 94, the study determined. The IQs of young men who smoked more than a pack a day were lower still, at about 90. An IQ score in a healthy population of such young men, with no mental disorders(心理疾病), falls within the range of 84 to 116.
An addiction that doesn’t discriminate(歧视)
“In the health profession, we’ve generally thought that smokers are most likely the kind of people who have grown up in difficult neighborhoods, or who’ve been given less education at good schools,” says Weiser, whose study was reported in a recent version of the journal, Addiction, “But because our study included subjects with various socio-economic backgrounds, we’ve been able to rule out socio-economics as a major factor. The government might want to rethink how it arranges its educational resources on smoking.
Making the results more significant, the study also measured effects in twin brothers. In the case where one twin smoked, the non-smoking twin registered a higher IQ on average.
Although a lower IQ may suggest a greater risk for smoking addiction, the representing data on IQ and smoking found that most of the smokers investigated in the study had IQs within the average range, nevertheless.
In the study, researchers took data from more than 20,000 men before, during and after their time in the military. All men in the study were considered in good health, since pre-screening(筛选的)measures for suitability in the army had already been taken. The researchers found that around 28 percent of their samples smoked one or more cigarettes a day, 3 percent considered themselves ex-smokers, and 68 percent said they never smoked.
“People on the lower end of the average IQ tend to display poorer overall decision-making skills when it comes to their health,” says Weiser. He adds that his finding can help address serious concern among heath counsellors at grade and high schools.

But science may have just proved them right – because beautiful women are more likely to have daughters than their plainer counterparts, according to a study.
As parents tend to pass on genes that determine looks, this could result in handsome men becoming rather thin on the ground. For example, Yasmin Le Bon is signed to the same modelling agency as daughter Amber, and Jerry Hall’s daughters Elizabeth and Georgia Jagger have both taken to the catwalk.
Dr Satoshi Kanazawa, of the London School of Economics, analysed data from a survey of 17,000 babies born in Britain in March 1958 and tracked them throughout their lives. When they reached 45, they were asked about the gender of any children they had.
Those rated as attractive were equally likely to have a son or daughter as their first child – but the unattractive sorts were more likely to have a son.
Dr Kanazawa believes that parents tend to produce children who benefit from their own features. So it pays for attractive women to have daughters. But couples blessed with strength and aggression rather than looks are better off having boys, as these characteristics are of more use to males.
A. Women are becoming more beautiful over the generations because attractive women have
more children than plain ones.
B. Single girls have always complained that good-looking men are difficult to find.
C. Beauty is of more benefit to a woman than a man.
D. At the age of seven, their attractiveness was rated by their teachers.
E. Put another way, the beautiful women were more likely to have daughters.
F. And it may also explain why many models have daughters who follow in their fascinating footsteps.
G. Famously good-looking parents like Tom Cruise and Katie Holmes are more likely to have girls than uglier couples.
