Higher Productivity — The Netherlands
If you have ever painted the walls of your home, you know that a large part of the time and energy investment is spent going up and down a ladder, and moving it further along after each stretch is done. Professional dry-wallers in Utrecht in the 1980s were fed up with this loss of productivity, and started working on stilts. Though perhaps slightly riskier than ladders, the stilts allowed them to work many times faster. A special crouching technique was developed for the lowest ends of the walls.
