Psychologist George Spilich and colleagues at Washington College in Chestertown,Maryland,decided to find out whether,as many smokers say,smoking helps them to "think and concentrate."Spoloch put young non-smokers,active smokers deprived of cigarettes through a serues of tests. In the first test,each subject sat before a computer screen and pressed a key as soon as he or she recognized a target letter among a grouping of 96.In this simple test,somkers,deprived smokers and non-smokers performed equally well. The next test was more complex,requiring all to scan sequences of 20 identical letters and respond the instant one of the letters transformed into a different one. Non-smokers were faster,but under the stimulation of nicotine,active smokers were faster than deprived smokers. In the third test of short-term memory,non-smokers made the fewest errors,but deprived smokers committed fewer errors than active smokers. The fourth test required people to read apassage,then answer quesstions about it,Non-smokers remebered 19 percent more of the most important information than active smokers,and deprived smokers bested thoes who had smoked a cigarette just before testing.Ative smokers tended not only to have poorer memories but also had troible separeting important information from insignificant details. "As our tests became more coplex," sums up Spilich,"non-smokers performed better than smokers by wider and wide margins". He predicts,"smokers might perform adequately at many jobs-until they got complicated.A smoking airline pilot could fly adequately if no problems arose,but if something went wrong,smoking might damage his mental capacity."

Hmmm, very interesting....thank you for sharing that. I do think that it would be interesting to see how non-smoking types that choose to gossip rather than assist customers and actually "work" impact future sales for a company too...I have seen this firsthand and from what I have seen, happy smokers seem to be able to accommodate consumer needs better than many of their non-smoking, gossiping counterparts who take excess breaks yakking to no end. Smokers seem to be more conscious of human issues and willing to look past minor "imperfections" and get right to the issue at hand, and more willing to try and help solve it... Interesting stuff tho, thank you. :)
