INDOLENCE

Indolence means laziness, idleness, sloth, lethargy, torpor, inertia, and slacking. It describes me in general, although here I am working at age 80. 

Derived from the Latin indolentia, which originally meant "freedom from pain" or "insensibility to pain" in the 1600s, before shifting over time to describe the avoidance of exertion ("taking pains").
