Triggers.

Consider the smells described in this chapter (Comments, Large Class, Long Method, Long Parameter List).

1. Which of these do you find most often? Which do you create most often?

2. To stop children from sucking their thumbs, some parents put a bad-tasting or spicy solution on the child's thumb. This serves as a trigger that reminds the child not to do that. What triggers can you give yourself to help you recognize when you're just beginning to create one of these smells?

See Appendix A for solutions.
