Is fluoride in our tap water a good or bad thing? Are there risks? And if so, what are they? And what about the 'dose? How many mg (of fluoride) per litre of water is safe? Or recommended? Why are some people saying terrible things about something that most of us have been consuming for our entire lives? And do they have a point? Oh, and what about this other thing called 'raw water'? What is it and why is it 'all the rage' (for some)? As someone who is 60% water (give or take), I found this chat super interesting and btw, Doctor Bill is a brilliant Scientist, amazing Teacher and even better Human. We're super lucky to have him.

Enjoy.
