Bertrand Russell On Smoking The London Hospitals study was the first British study to investigate possible causes of the growing epidemic of lung cancer. It was published by Richard Doll and Bradford Hill in 1950. Bradford Hill was a statistician, and Richard Doll was a young doctor. In the study, several hundred lung cancer patients in London hospitals were questioned about their past smoking habits and other behaviours, to see whether any pattern emerged. Many years later, Sir Richard Doll wrote: By the time we had data on several hundred patients it was obvious that the principal difference between the patients with and without lung cancer was their smoking habits, and we had to make up our minds whether the association was due to chance, bias, confounding, or to cause and effect. The evidence that led us to conclude that it was due to the last (and which led me to give up smoking in 1949) is described in our first paper...

bacteria

A few scientists have long held the belief that human cancers might well be caused by bacteria. Not that many years ago doctors were surprised to learn that peptic ulcers and cancers of the gut might actually be caused by acid-resistant bacteria. Why were they surprised? TB a precursor to lung cancer used to be mainly a disease of non-smokers, the tobacco smoke having antiseptic properties, was thought to inhibit susceptibility to TB. In the 60's doctors became alarmed that, with the immense reduction in TB, lung cancer was on the increase in the smoking population. They jumped to the conclusion that cancer was caused by smoking. How they must be dismayed by recent studies that show that aspirin, another chemical which has bacteria-resistant properties, has been shown to inhibit human cancers.The evidence is there for all to see, bacteria cause a range of diseases in human-beings which lead to cancers. An aspirin a day, or 5 Player's Weights? Your choice, but I'm waiting...

Smoking

His baton was a Malboro Red.......He'd hold an unlit cigarette an exceedingly long time, until it became fixed in the minds of his audience like a handgun. Then he'd make a grand production of striking a match and bring the flame to the cigarette tip. The next rounded phrase that fell from his mouth would be encased within a dollop of smoke. Then, when he flicked his ash---tap, tap--- everyone leaned forward and watched closely, as if Willie Mays were tapping his bat on the home plate. Something interesting was about to happen. At last, he dropped the burned match into the glass ashtray with a light plink , he delivered the punchline or came to the crucial point, and I was tempted to yell, "Bravo!" J.R.Moehringer

Smoking and health

postulate: Smoking is unrelated to lung cancer Recent studies suggest that lung cancer may be a genetic disease There are no studies showing that nicotine is a carcinogen. August 1, 1990 edition of the Wall Street Journal . A Study was conducted by researchers at Louisiana State University Medical Centre (New Orleans): Albert Einstein College (NY). The researchers studied 300 families in Southern Louisiana, who had a history of lung cancer, and compared them with 300 controls. The researchers concluded lung cancer is an inherited disease. Based upon retrospective studies 35 the researchers concluded that if a person had two copies of the lung cancer gene, his chances of getting lung cancer by the age of 50 would be 14% if he did not smoke, increasing to 27% if he were a heavy smoker. In the more likely case of an individual having only one copy of the gene, the researchers concluded that a non-smoker would have practically no risk of getting lung cancer by age 50, but for a heavy ...

A-levels

In 1965, when grades were first awarded, 10% of places were to be allocated for As and 20% for Es. In other words you were assessed against your peers, thus sorting out the best candidates for higher education, which was then free.
