And in addition to those excellent reasons, here is another one. If you
forget to check a condition (or a result code for that matter), you can
get wrong results without knowing it. If you forget to catch an
exception, the program will crash, but you'll know it.

Remember: there is only one thing worse than a program that crashes: a
program that gives wrong, but likely results.
