I've gained quite a bit of exposure over the last couple of years to the modern art of processing resumes. Suffice to say that practically no one actually reads resumes themselves any more; they read the output of automatic resume preprocessors that cherrypick keywords. The more keywords in your resume, the more qualified you are.

It goes without saying (or should, although I guess I'm saying it) that someone with long years of reasonably diverse experience is going to have a lot of keywords, and is going to rank highly on a relatively larger percentage of the available requisitions.

God help you if you have language in your resume saying "I have NOT done the following things..."
