I’m 39 and I see my doctor once a year, at most. This year I had a urinary thing. Last year and the year before that I had a rash. The year before that I didn’t go. For all of my twenties I went three times. She still remembers me just fine, asking how is my CrossFit doing.
I see my wife’s doctor more often than my own because he is also our newborn son’s doctor.
They both have thousands of patients. The waiting rooms mostly have elderly, parents with their newborns and obese people.
