Unnaturally languid, lazy, indolent.
I'd be more apathetic if I weren't so lethargic.

The big tired where you can't do anything and you can't feel anything even though you have no particular reason not to

Lethargy is lying on the floor and thinking about nothing as five hundred trains if thought trundle aimlessly through your head before nosediving straight off a cliff
"Why not get out and get some vitamin D, even if you don't feel like it? Better than spending another Sunday afternoon in lethargy.

An extreme state of lethargy, cause unknown, but very tiring. Seismic Lethargy can strike down its victim without warning and usually whilst they are trying to do something. It usually affects young males and reported cases are more prevalent in the warmer summer months. The consensual course remedy is to remove the patient from the environment that is inducing the lethargy.
Rhys is unable to continue today because he is suffering from Seismic Lethargy.

an economic state of a labor shortage where employers create incentives for job applicants, but very few people work due to a prefference of staying on social programs and handouts, rather than seeking employment.

EX: People that work ready and healthy staying on Unemployment Insurance due to extra weekly payments as opposed to seeking employment.
We must live in the Great Lethargy because employers would have turn away applicants during the Great Depression, if those employers were giving out hiring bonuses etc.
