How many of you have taken that widely circulated quiz to determine your “real” age?  You know, the one that gives you a “health” age as opposed to your chronological age?

It turns that the “quiz”  is a veiled attempt to extract health-related information from you that all sorts of marketers can use.

As the superb story in today’s Times points out, people reveal information in the course of doing the quiz that they almost certainly would not routinely disclose.

So if  you do the quiz and  then get an email about Boniva three weeks later, you’ll know why.
