Many medical conditions had not yet been recognized when you and I were kids! I think back on my grade school classmates, and suspect the ones who seemed stupid were probably dyslexic. Others were probably malnourished. Some had ADD, I'm sure. Some of them stumbled through school, others dropped out. Nowadays it seems as if the pendulum has swung too far the other direction, and kids are getting labels stuck on them unnecessarily, and taking dangerous prescription drugs because of it. Hoping we find the middle ground some day.
