Smoking Is Bad for the Brain?

Smoking not only damages health, it is bad for the brain too, according to a Scottish study spanning nearly 60 years. Professor Lawrence Whalley and his team looked at how the cognitive abilities of 465 people, half of them smokers, changed over their lifetime. Smoking is strange behaviour. Almost every smoker knows that it's bad for his health, but many smokers continue the habit for decades, each year experiencing a further decline in health and well-being. Looked at rationally, smoking is quite disgusting. It stains the teeth and the fingers, causes bad breath, and creates an unpleasant environment for non-smokers.
