You should rewrite your resume for every job you apply for, not a complete rewrite but read the ad for the job you are going for and edit you resume to fit that job. Pay particular attention to their wording and throw it back into your resume. If they say "we are looking for someone who likes to wear brown shoes and a black hat" be sure you put that in there.
I learned that from a drunk, slut, nurse, that I used to know who had her own business and it works wonders. I have even cut and pasted sentences from the online ads into my resume. I know it sounds stupid but many HR people are running on autopilot and when they see there own buzz words coming back at them they get all excited.
Age and treachery will overcome youth and skill.
