When I was a little boy, many shoe stores had an unusual machine called a fluoroscope. It was designed to help customers see whether or not the shoe fit.
The problem was that the fluoroscope was actually an x-ray machine. You see, in those days we did not know that x-rays were dangerous and that the human body can only receive a limited amount of x-rays in a lifetime.
If you have ever received an x-ray, you know that the technicians hide behind lead-filled walls. That means being a shoe salesman in the 1950's was a high risk vocation!
You can see one of those old fluoroscope machines on display at the Children's Museum here in the Museum District of Houston.
I suspect there are things we take for granted as normal and good today that one day we will see was hurtful and destructive. What do you reckon they are?
God is wise. Aware of the x-ray problem in those days, he also knew that people only got new shoes every few years. Over exposure was not a problem.
