My dad was programming right until his retirement. He always refused any sort of management role (though he occasionally got a lead role for a high-profile project thrust upon him). I know one of the things he worked with was Java, so it definitely wasn't all old stuff. He was working on an open source project in his spare time, though strangely that seems to have stopped since his retirement. I should ask him about that.

I'm 40 and still young. I'm learning tons of new stuff, developing into new areas, and started as a freelancer two years ago (which boosted my pay quite a bit). I still have great plans to work on ideas of my own in the future. No idea where I'll be in 10 years, but I bet it's something totally different.
