I manage to hack my way through computers. As for Grandkids. Mine are over 16, except for the youngest, 10. He plays computer and handheld games and watches TV. He is as smart as a whip, in gifted program and reads over a twelveth grade level. He is underweight and not fat, like we hear about on the news. He hops and skips instead of walking. Most adults would like to be as smart as he is.
