People who believe they're going to get harmed by statins, get harmed.
This by contrast with the "placebo" effect, whereby you anoint your little dough-ball with a few drops of aromatherapy, and it does you the world of good.

Not everybody - just enough to lift compulsory vaccination up the news agenda.
Call me paranoid, but I think I detect the beginnings of a soft campaign to disdain any idea that vaccines could ever be harmful - and I also think I'm old enough to have heard that before.
And if people are genuinely uneasy about vaccines, believing them to be potentially harmful, what then?
