Second point made by Priscilla -- the surge in retirees from that core motivational group -- I am in awe at the quality of substitute teachers and assistant teachers in my county. Intriguing too when the substitute "assistant" is a PhD. I find it bumps up the conversational level with the children on WHY are you HERE -- e.g. what is an education FOR? -- and then making real connections for them on learned abilities and their personal future choices.
