Lying down on the job?

It may look comfortable, but installing the summators was seemingly neck-breaking work. To reach into the tile, you have to lie on your stomach. Your hands are busy connecting cables so you can't support yourself with your arms. And, holding your head out to see what you are doing puts a strain on the neck.

Add to this the constant climbing up and down off the 2-metre high tiles and by the end of each day we were all exhausted.
