"Sometimes a resistor gets mismarked; sometimes a resistor’s value shifts due to aging, overheating, or temperature cycling."

"Resistors are certainly the most basic passive component, and, barring any extreme or obscure situations, you won’t usually run into problems caused by the resistors themselves. ... In other cases, some other part of the circuit may be causing damage to a resistor, and the failure of the resistor is just a symptom of a larger problem"

Skipped Chapter 2. With the intention to go back to it to do an in-depth treatment.
