the.com/exertion
The tax your body bills you for doing anything worth doing.
means The physical or mental effort you put into doing something demanding.
from From Latin exertio/exserere, a combo of ex- ('out') and serere ('to join, bind')—literally 'to thrust out' or 'put forth.' The Romans used it for sticking out a limb or pushing something into view; English borrowed it in the 1600s-1700s and redirected it inward, toward the forth-putting of effort and strength rather than body parts.
