When I showed this "then-and-now" photo to my life-long friend John, he posed the following questions: How are these two people different? How are they the same?

Are we essentially the same person at 60 that we were at 25? Or does a lifetime of experiences change us? I seem to recall reading that our personalities are fully formed at a very early age. So most of the changes are physical (and inconsequential)? The "me" in my head feels exactly like that younger version. And maybe that’s the answer to John’s question. The differences are all positive. If I had to pick one, I’d say I’m a little wiser. But only a little.
