Maybe it's the middle-aged-me talking, but does it seem to anyone else that your entire year can be taken up with one doctor, doctor-related, specialist appointment after another? And add to that the interspersed veterinary appointments and I swear I am in some waiting room every month! Did my annual check up, to be followed up by mammogram, annual dermatologist body check, eyes checked, gyno check, dentist check, Scrappy check, Bernie check, Boyz check, Cookie check, etc. And, although I am very lucky to have insurance, the co-pays are popping up all over. I never had to pay a co-pay for the bloodwork for my annual exam. Do now. Never had to pay a co-pay for the mammo. Do now. And...because I couldn't get in to see my actual doctor for my annual exam, I am expected to come in for a six-month follow-up. I say - if you don't trust your nurse practitioner, go hire someone else. Once a year is waaay plenty enough for me.
Just my two (and growing) cents on the subject.
