A physician who is too thorough in conducting a medical checkup is likely to subject the patient to the discomfort and expense of unnecessary tests  One who is not thorough enough is likely to miss some serious problem and ttherefore give the patient a false sense of security  It is difficult for physicians to judge exactly how thorough they should be
Ttherefore, it is generally unwise for patients to have medical checkups when they do not feel ill
Patients not medically trained are unable to judge for themselves what degree of thoroughness is appropriate for physicians in conducting medical checkups.
