• Generally, less code is easier to understand than more code; however, there is a point at which code is so dense that it becomes hard to read.

• Code is read much more often than it is written.

• Code frequently lives longer than we want it to.

• The person who tests or maintains a piece of code is frequently not the original author.

• At scale, the skill level of developers reading/writing/maintaining/testing code is going to be a normal distribution around the mean of "not expert."
