Since living in Belgium, and that was from 1963 onwards, I do not believe any family doctor has ever insisted that we have regular, yearly or bi-yearly or whatever physicals.
In Belgium, the custom was that if you were sick or ill, you went to the doctor for treatment, but that otherwise they did not push their services. Belgians, Europeans in general I surmise do not like being subjected to such practices.
I know that when we lived in the US my mother often became incensed and really worked up when the dentist sent cards saying it was time for our yearly check-up. She found such behavior to be unscrupulous, grubby money-grabbing, undignified, crassly beneath an educated person's dignity and only meant for the personal enrichment of doctors/dentists. She couldn't stand it. She found it a sort of advertising and in most Euro countries, doctors, lawyers, notaries and such are forbidden by law to advertise their services.
The only time I was told to get regular check-ups was after I had a pneumectomy due to a benign cancer. Then all doctors recommended regular check-ups as follow through. At least bi-yearly. But by the 5 or 6th year the check-ups became less frequent and when my regular oncologist moved elsewhere, they sort of fell off altogether.
And here I still am. 45 years later without getting regular physicals or checkups.
I guess it's like 'no news is good news', 'let sleeping dogs lay' and 'you've surpassed your predicted date of passing anyway, so count yourself lucky.'
So, I still only go to a doctor if something is wrong or to fulfill medications.
And I guess that I've been pretty lucky so far as well.
