kw: dental care
The number of people who report that they floss their teeth daily ranges from 22% to 48%, depending on how the pollster asked the question. Prior to about age 32, I was one of those who did not floss, and nobody had been able to convince me that I ought to do so. Then, when I went to graduate school, and moved to South Dakota, I got a new dentist.
A friend recently mentioned why he flosses: He was told, "Just floss the teeth you intend to keep". It is all in how you say something!
