Yesterday I saw a 5 year old walking 60 feet from a restaurant to the family car with a smartphone in his hands, he never looked up from the screen, the mother was guiding him by grabbing his shirt collar… even when climbing into the SUV he never lifted his eyes from the screen…
It comes from a lack of understanding of the basic physical concept of heat and cold. Increasing heat needs an increase of energy output. Increasing cold needs an increase in energy transfer from one location to another. People are still confused about cold not being able to be radiated like heat.
I remember those:-)
