When I was growing up, there was a great controversy about whether fluoride should be added to drinking water to combat tooth decay in children.  In the end, science ’won’ and children’s teeth have been much healthier since.

Now we have a need to combat another problem. Politicians have become very adept at ignoring science and ‘going with their gut instinct’ or, far more likely, political expediency. The Donald is twitterific in his criticism of the press and others who hold opposing views. ‘Fake news’ he asserts, ignoring anything factual or scientifically proven if it conflicts with his personal view.

We desperately need a new fluoride -a magical potion that can combat this ‘truth decay’.
