Enrolling healthy, young adults crucial to success of new healthcare law

At the headquarters of Public Health — Seattle & King County in downtown Seattle, those leading the county's effort to get people to sign up for insurance under the new federal health-care law are conspiring around a table. Maybe they could get singer Dave Matthews to urge everyone to get covered, one suggests. Macklemore, sighs a young woman, intoning in a hushed, reverent voice the name of the rising star of Seattle rap and social justice. For the growing campaign to enroll the uninsured in health insurance as part of the monumental health-care overhaul, signing up healthy young adults — the "young invincibles" — is crucial to success.
