Dentistry

I'm indebted to my friend Kevin, who also happens to be a first class dentist for this five-minute clip.

I first went to a dentist when I was about 13, it was a Mr. Pitt-Ford.  He was an old bloke and his equipment was also very old, although at the time I had no way to judge that.  The drill was driven by a pulley system, which although smooth, went at about 1000th of the speed of the modern ones we are all used to.  My how things have changed in the last 60 years!
