Mephistopheles

Good! A remedy Without physician, gold, or sorcery: Away forthwith, and to the fields repair, Begin to delve, to cultivate the ground, Thy senses and thyself confine Within the very narrowest round, Support thyself upon the simplest fare, Live like a very brute the brutes among, Neither esteem it robbery The acre thou dost reap, thyself to dung; This is the best method, credit me, Again at eighty to grow hale and young.
