Low speed
Today, we have many appliances to work for us. Some of these have "low-speed" or "low power" settings, like hairdryers, microwave ovens, or refrigerators. This enables this equipment to operate at a partial energy output.
But what if the dial got stuck and any of these devices could not operate at maximum power?
What about people? Do we operate at "low-speed" by our habitual inactivity? Have we even known what it is like to operate at a higher power? Or is our dial "stuck" on low?
I think it may be that a large portion of our population is so habitually sedentary, and have been all their lives, that they would not even know if they had this problem!
Is ignorance bliss?
