Narrator: This is Science Today. Americans are living healthier lives and reducing their risk of heart disease. That's according to a recent study conducted at the University of California, San Francisco. Doctor Lee Goldman, the study's lead author, says Americans are living longer because they are smoking less, eating healthier and lowering their cholesterol.Goldman: We looked to see whether these changes in risk factors really made a difference and also whether the investments made to change those risk factors were worth it. We found that the investments required, both in terms of public health campaigns and medical treatments to reduce these factors were well worth the cost.
Narrator: Despite these recent successes, however, Goldman warns that the battle against heart disease is far from over.
Goldman: The study is really more of a congratulatory pat on the back. One of the reasons why people sometimes give congratulatory pats on the back is because you're trying to encourage people to keep up the good work rather than telling them that the job is finished.
