Why do people use industrial machinery?

I have a job that involves a lot of physical work, and that includes cleaning machines, vacuuming, and other tasks.

When it comes to making and selling stuff, I’m usually using a computer or an electronic device to do most of the work.

But my boss keeps telling me that I should be using my eyes, my ears, and my hands.

He says that they’re better suited for other things.

So, how do I improve my eye and ear skills?

And why do people prefer using the fingers to make things?

These questions and more are addressed in the second part of this series on the cognitive processes that lead us to make and buy things.

Part two will be published next week.
