Exhaustion is a rich persons disease. An ordinary person cant come into a hospital and say give me a bed; Im exhausted.
I heard some late night comic say that. David Brennan, maybe?
A few decades ago, the fashionable term was "nervous breakdown." Intellectuals, artists, poets, celebrities, and other sensitive types were allowed to be hospitalized for nervous breakdowns. The publicity surrounding their hospitalizations gave them a kind of mystique, e.g. Sylvia Plath and James Taylor.
Then when the term began to be applied to too many ordinary people, it lost its cachet.
