(KCEN) -- A study suggests too much TV for kids might turn them into aggressive adults.
The study included 1,000 children born in the early 70's in New Zealand.
Every two years between the ages of five and 15, they were asked how much television they watched.
Those who watched the most were more likely to have a criminal conviction and have more anti-social personality traits as adults.
This does not prove cause and effect, but the American Academy of Pediatrics recommends no more than 1 to 2 hours of TV for kids a day.
