The transfer may be Carelessness, or Slothfulness, or Gluttony, or one of the Dissipations in food, drink, work or play; or it may be even Egotism, which is sometimes a poison: but they all take you to Sick Street. Don’t get a transfer down Sick Street. The road is rough, the scenery dismal, and at the end is the cemetery.”
