The team shows how ergonomics makes life more comfortable. Astronauts can brush in space thanks to a very clever invention. They use a foamless toothpaste that doesn't need water, has a pleasant taste, and is perfectly safe to swallow.
Edible toothpaste is just one example of ergonomics at work.
In other words, ergonomics refers to the natural laws of work. It's the science of designing the job, products, and place to fit the worker. Ergonomics enters into the design of everything from equipment for space missions to the most comfortable car interior or athletic shoes. The idea behind it is simple. If you use a tool to do something it wasn't designed to do, then the tool can be damaged.
