Went with Mrs W to see the Nurse at our local Surgery this week and this caught my eye. In the corridor near the nurse's room there is a wall mounted height measurer. Stand with your back to the window frame in this case as that's where the measure has been attached and slide the scale up and down until it rests on top of your bonce. Take a look at my artistic representation of reality: Notice, the floor immediately beneath the measure is uneven. In order to be measured properly, one needs to lift up one's right leg to counter the slope of the floor that begins immediately below the measure. Alternatively, just stand there and be measured inaccurately. The wonders of modern applied science! Not a massively serious problem but a bit more thought could have been taken! DW
