+It would be thought a hard Government that should tax its People
+one-tenth Part of their _Time_, to be employed in its Service. But
+_Idleness_ taxes many of us much more, if we reckon all that is spent
+in absolute _Sloth_, or doing of nothing, with that which is spent in
+idle Employments or Amusements, that amount to nothing. _Sloth_, by
+bringing on Diseases, absolutely shortens Life. _Sloth, like Rust,
+consumes faster than Labor wears; while the used key is always bright,
+as Poor Richard says. But dost thou love Life, then do not squander
+Time, for that's the stuff Life is made of, as Poor Richard_ says. How
+much more than is necessary do we spend in sleep, forgetting that _The
+sleeping Fox catches no Poultry_, and that _There will be sleeping
+enough in the Grave_, as _Poor Richard_ says.
