THE BRONX - According to a new study by the American Heart Association, kids today don't run as fast or as far as their parents did when they were young.

The association says it takes children 90 seconds longer to run a mile than their counterparts did 30 years ago.

Experts say it's a combination of lack of motivation and exercise, with many schools relying solely on recess because they no longer can afford physical education programs.

Health experts recommend that children get 60 minutes of activity a day.
