Who Teaches the Teachers?

How often does the average person remember an opinion or bit of knowledge they once held, so long ago, but swept aside without realizing it as time went on? How often, then, does that opinion or bit of knowledge seem somehow deeper and more fresh than current perspective or understanding?

Every so often it does one good to learn again the most basic of facts, just in case you left a few things behind in your hurry to grow up. Every so often, adults should watch Sesame Street.

Seriously.
