Agree. I'm in my mid 50s; I figure anything more than another 15 years or so is a gift. That doesn't sound like a lot of time in retrospect; thinking about 2006 does not seem like very long ago to me. So there's a growing sense of there not being a lot of time left, and a stronger desire to spend it on simple things that give me satisfaction rather than building more software that will be obsolete before it's really even finished or learning new technologies that will be "legacy" by the time I can really be productive with them.

At the same time I have zero interest in longevity. I will live the life I've been granted, for as long as it lasts. Then I'll get out of the way.
