My career is in the health field, that in addition to all the volunteer hours and fund raising efforts I do in regards to HIV, gives me an insight where I can truthfully tell you that methods attempting target an audience and get them to STOP or CHANGE a lifestyle that carries a high risk for potential HIV exposure is only a fraction as successful as the campaigns geared towards a target audience that has not developed those traits (or addictions) yet.
Just using myself as an example, I think you are dead right on this.
Nothing else of course.
Only kidding. The reason I actually like Getbig boards is because there is a good back and forth between people. And I do think there is a good portion of liberals and conservatives here as opposed to many other sites.
