Best explanation I've heard for the ADHD epidemic:
Our kids are now amazingly stimulated by a huge variety of media from birth. They live in a world that is EXTREMELY stimulating and with constant diversions such as computers, television, music, handhelds, etc.. etc..
Then you take them and put them in a completely non-stimulating environment where a person stands in front of the class, trying to teach them "boring" stuff (in comparison to the media they're accustomed to consuming).
Then when they don't/can't pay attention, we label them with ADD/ADHD and give them drugs to help them focus.
In this world of sin and sorrow there is always something to be thankful for; as for me, I rejoice that I am not a Republican.
