1. Too much time spent playing violent video games at an early age is brain-mapping 6-10 year olds to run combat scenarios, reinforced by thousands of hours of repetition.
I agree with this. There was a time when realistic combat games were only played by people training for the military, because in the military, you have to be able to kill people when necessary. But now, all the kids play these games and it makes shooting people like second nature. Parents really need to make sure their boys aren't playing games rated M for mature. Those games are very, very realistic.
