<p>In lots of the world, and in lots of cultures, it’s the norm for people (well, boys mainly) to do several years of military service or missionary work at your age. Graduating from college in their mid-20s is the norm for them. Once upon a time, at an important juncture in our history, it was the norm here, too: over half of my father’s graduating class at college in 1951 were veterans on the GI Bill. We call that “The Greatest Generation”.</p>
