torpitude

Torpor:
1 : APATHY, DULLNESS
2 : a state of mental and motor inactivity with partial or total insensibility : extreme sluggishness or stagnation of function

Turpitude:
: inherent baseness : DEPRAVITY ; also : a base act

The latter word I learned from Bloom County.

The other day I wondered if I was projecting my inability to function after 10 p.m. on a friend. I was not: she too shuts down and longs for her bed.

Torpitude: the craven propensity to take too many naps or need to go to bed earlier than normal people. My first new word since "stomple."
