My girlfriend is a biologist with the National Parks Service and all of their resumes are expected to be three to five pages long. It hurt my soul when she told me that.
It's actually easier - you just tag on whatever you do every one in awhile. "Normal" resumes are like ads for you, and the positive/negative usefulness of your resume is more about your ability to produce compelling bullshit for an audience, miss the mark, or land in the middle of the bell curve.
