Patient in ICU has had type 2 diabetes for years. Family at bedside. Sugars "out of control" high. Physician chooses to write for subQ insulin, which RN gives.
Family goes home after dinnertime and gradually patient's sugars plummet.
Turns out family had been sneaking the patient candy all day without telling anyone.
This has happened to you, too, hasn't it. (Notice ungrammatical lack of question mark.)
Why do we keep interfering with natural selection?
