There’s a good article over on Dick Puddlecote’s blog about those killjoys at Public health.
Here is one paragraph that the health zealots think of us, the great unwashed public.
“Lifestyle” is a loaded term that reinforces stereotypes about individuals and a world view that people are majorly or entirely responsible for their own health. Indeed surely the term “death style” would be better because the logical implication is that most individuals in our society are consciously choosing to lead unhealthy lives. Using such a term ignores the many and varied influences on health; the implicit assumption is that all is solved by developing an individual’s rational health decision making capacity.
Go and read Dick’s post. He makes the counter argument better than I ever could.
