Under pressure at St Mary's

 

I've begun to notice that the floor in some pews is very pitted. Physics text books always give examples of stiletto heels being banned on wooden dance floors. Here's the evidence. The books go on to explain that the small surface area on the end of the heels means a high pressure and that it is pressure that results in damage, not the size of the force itself, at least if that's the weight of a human being.
