It seems like these kinds of &quot;studies&quot; are only made to write headlines and to write books (notice how half of the people quoted in the article have some surprising new &quot;facts&quot; that they reveal in a book they wrote?).<p>The only paradox is why researchers still latch onto a calculation of health based on just height and weight that was concocted in over 150 years ago. What other field would rely on such a primitive, outdated formula and use it as the base of research?
