Laziness (also known as indolence or sloth) is emotional disinclination to activity or exertion despite having the ability to act or to
exert oneself. It is often used as a pejorative; terms for a person seen to be lazy include "couch potato" and "slacker". Related concepts include sloth, a Christian sin, abulia, a medical term for reduced motivation, and lethargy, a state of lacking energy.
