They are up from 3 days in 2000. North and South Dakota tied for first place with the fewest number of days of activity missed. And Vermont, which ranked highest on 14 of 22 indicators, tied for 14th place on mental health -- a drop from 9th place last year. The rankings are based on information obtained from the Centers for Disease Control and refer only to the previous 30 days.
