And now for a new regular feature of the blog: Useless Product Innovations.
Water filter jugs are a pretty straightforward product. You pour water into the chamber at the top of the jug, it trickles down through the replaceable filter cartridge, and the filtered water sits in the bottom part of the jug, ready to pour. It’s not the most essential item, but it has a clear and simple purpose, and provides some value: if you’re in a hard water area, it does make tap water taste less minging, and reduces limescale in other appliances like kettles and irons.
Of course, I’m not saying I don’t believe dentists exist. I’ve experienced enough sensory data to be pretty sure they do.
Nor am I saying that I don’t believe we need dentists. Obviously, dental problems happen and we need specialist tooth doctors to deal with them.
What I don’t believe in is the paradigm which holds dentistry to be of such preeminent importance. The paradigm that says we need quite so many dentists. That says dentists should operate independently of the rest of the medical system. That says they should provide their own first line inspection function. That says we need routine dental check-ups whether or not we have any reason to believe we have a dental problem.
