Benjamin Franklin, a letter to the Royal Academy of Brussels, 1781

"He that dines on stale Flesh, especially with much Addition of Onions, shall be able to afford a Stink that no Company can tolerate; while he that has lived for some Time on Vegetables only, shall have that Breath so pure as to be insensible to the most delicate Noses; and if he can manage so as to avoid the Report, he may any where give Vent to his Griefs, unnoticed."
