It is hard to know...
I see a lot of patients whose entire life seems to revolve around Dr. Appointments just to make sure...
Of these, it is mostly women that stay on top of things and of the men... many are there because of their wife.
My Grandfather had never seen a Doctor or Hospital until his late 80's... even his reading glasses were over the counter.
He had a bad accident with a log splitter... lost 3 fingers.
While at the Hospital they noticed an irregular Heart Beat and wanted to put in a pace maker...
He flatly refused... lived another 6 years still working around the farm before he passed from his heart condition.
He was very religious as most of the farmers from that era... said when his time is up it is up.
Being 87 and never seeing a Doctor and then only because of a farm accident... he also delivered several of the kids because the snow made the roads impassable... said it was better to deliver at home than stranded on the road in a blizzard.
Something to be said living life on your own terms.
Like his contemporaries... he never retired.
