It's always interesting to see how current science eventually catches up with SOP.
I don't think they will ever figure out that it's better for kids to start school at 8 years old, rather than 5 or 6. Or at least I highly doubt that we'd hear it in the mainstream media.
Actually, a number of years ago I did hear somebody on the radio talking about a study that had been done in Sweden or somewhere that showed that kids did better if they were able to be kids longer before going to school, or something like that.
