I turned 40 today.

Not surprisingly, the world didn’t end or spin off its axis, and the four horsemen of the apocalypse didn’t turn up either.

Instead, I spent yesterday and today surrounded by people I love, doing things I enjoy — and for that I am ever so grateful.

And now, feeling reflective and perhaps a little nostalgic at the end of a weekend well spent, I thought I might share something with you that means something to me. The footage is not mine, and like me it’s not perfect. But sharing it is my way of thanking you for being part of this crazy ride: a clip of U2 playing their beautiful song Bad in Berlin late last year, followed by the usual song they finish their concerts with.

Appropriately, that song is called 40.
