Cunning leads to knavery. It is but a step from one to the other, and that very slippery. Only lying makes the difference; add that to cunning, and it is knavery.
While strength and years permit, endure labor; soon bent old age will come with silent foot.
[Lat., Dum vires annique sinunt, tolerate labores.
Jam veniet tacito curva senecta pede.]
