What is it?
Referring to “spoon theory,” a metaphor for daily energy, the number shown on this meter decrements each time the chain is pulled. The only way to refill the meter is to wait 4.8 hours.
“Spoon theory” is an idea created by disability activist Christine Miserandino to illuminate how those with chronic illness only have a certain amount of energy to do things in a day.
This is broadly applicable to energy in general–we only have a fixed amount of it each day, and it is okay to choose how it is spent.
