On Thursday’s episode of “The Dr. Oz Show,” Donald J. Trump told Dr. Mehmet Oz that he didn’t get much exercise these days. This is not really true. Even as he said it, he was in the middle of conducting a one-hour spinning class.

Mr. Trump’s much-hyped appearance came in the midst of a news week focused on the presidential candidates’ health. And Mr. Trump, the former host of “The Apprentice,” stage-managed it like a reality-TV reveal.

After days of will-he-or-won’t-he, as to whether Mr. Trump would provide the findings of a recent physical examination, daytime’s favorite doctor walked the candidate through a self-assessment, which Mr. Trump, as is his wont when self-assessing, answered favorably. If you feel so confident, Dr. Oz finally asked, “Why not share your medical records?”
