A new study conducted by Harvard University and Boston Medical Center says the best way to cut kids' screen time is to lead by example.
Young children often copy the behavior of adults, most often their parents.
The study was conducted at a fast food restaurant and found the majority of parents were using their cellphones while dining with their children.
The kids sitting with parents distracted by their phones were also more likely to misbehave.
Researchers suggest parents avoid using mobile devices in front of their children, especially while driving and during meals.

Researchers at Harvard University led a study which links exposure to the chemical formaldehyde to an increased risk of ALS.
The study involved more than one million adults. Funeral directors had the highest exposure to formaldehyde and were three times more likely to die from ALS than those with no exposure to the chemical.
ALS is a progressive, neurological disease with no cure. The disease was the inspiration for last summer's ice bucket challenge.

A new study conducted by the University of Colorado Denver School of Medicine reveals substance abuse may cause long term brain damage in women.
Researchers compared the brains of healthy adults to the brains of people with a history of using cocaine or other amphetamines.
Women who were former addicts had significantly less brain volume in areas linked to decision making, emotion and habit formation. Women who have not used drugs in over a year were still affected.
There were not the same brain differences in men.
Experts are hopeful that this study will lead to improved substance abuse treatments.
