If you travel enough, you start to notice something odd. The longest- lasting, most admired buildings in almost every city are the temples and churches. Glass offices come and go. Grocery stores close and reopen with new names. But the temple stands. Solid. Purposeful. Built for the long game. On a recent trip to Nashville, the great temples there reminded me of a truth that hits harder in your 60s than in your 20s. You and I are temples too.
