1 pints a day causes cancer. Are they serious?

It's all a load of rubbish. They'd just as well say "living causes you to die, so stop doing it!!!!!" Look how many of these so-called scientific warnings are proved to be wrong or flawed - from the coffee scare to fats. I believe that the most dangerous thing about these warnings is the fact that gullible people will worry unduly about them - and we all know that stress gives you heart disease! ;-)
