Modern culture has scientific studies for all sorts of questions. We know how many things are harmful to our health, in fact we sometimes get a feeling that we should rather stop living because anything we do/eat/choose is somehow damaging. But then we carry on living in the very same way we know is harmful. My heart has to be seriously damaged due to the vast amounts of caffeine that I have drunk over past years and yet I love coffee so much I am not going to stop drinking it any time soon. Am I carefully balancing the pros and cons of another cup or am I just being stupid?
