Fewer children in Ireland are drinking, smoking and having sex.
According to a new study into the behaviours of school children between the ages of 10 and 17, almost two-thirds of young people say they've never had an alcoholic drink - that's an increase of six percent since 2014.
It finds one in five children has tried e-cigarettes at some stage, but only one in ten tried smoking - a drop of five percent.
The study shows bullying's on the rise, with just under a third reporting being bullied - while one in ten children say they don't get enough exercise.
There is also a reduction in the number of 15-17-year-olds who reported having sex, down 3 percent to 24.
