What is a common "changer" we use every day?
It is an electrical transformer that recharges the battery in your mobile phone, powers your laptop, television, refrigerator and many other devices. It changes voltage and current to supply each particular appliance. The bigger the voltage and current change the bigger the transformer. How do they react to change?
They all create magnetic field around them which is invisible but enables the change.
By changing one level into another they warm up and have to be cooled down otherwise they burn out. Some of them also vibrate and produce noise, especially the older and bigger ones. When switched on, voltage or current levels do not change smoothly into the transformed levels, they alternate quite significantly before they stabilise.
How about us? (Not that I want to compare ourselves to machines, not at all.) How do we react to change?
Going through change costs us energy. We warm up, sweat, fear, suffer pain, shout, and cry or hold it all under a lid. The truth is that significant amount of energy is dissipated during this process and after a while we have to chill out otherwise we burn out. Blown up transformers are no good and neither are humans.
The good news is that the more you practice changing the better you get at it. You will become one hell of a transformer!
