The thirst for knowledge about health tapers off a bit as adults move through their 50s, but a new peak in interest occurs about age 65.

Researchers speculated that the reasons for what they call "the change points" are because when adults turn 50, they are often bombarded with suggestions from doctors about tests they should undergo, including mammograms or prostate cancer exams. When adults turn 65, they become eligible for Medicare and many take advantage of the free screenings available.
