<unk> s" are used as a metaphor and visual representation for energy rationing.<unk>  is a metaphor that is used to describe the amount of mental or physical energy a person has available for daily activities and tasks. It was developed by Christine Miserandino in 2003 as a way to express how it felt to have lupus. She used<unk> s to provide a visual representation of units of energy that a person might have and how chronic illness forces her to plan out her days and actions in advance, so as not to run out of energy, or<unk> s, before the end of the day. It has since been applied to other phenomena, such as other disabilities, mental health issues, marginalization, and other factors that might place an extra – often unseen – burden on some individuals.
