Unsurprising really - most older programmers I know are fed up with solving the same problems over and over again with whatever the new technology happens to be. After a while, writing what amounts to CRUD by and large is pretty dull.
If I want risky projects that might be spectacular failures, I'll do them in my spare time -- I really don't want those in front of the people signing my pay cheques...
I would think that the same is true with career management, especially after you 30 something and have a family to worry about.
But to be honest, the amount of age discrimination in our industry has me really scared about getting older.
I've been programming for > 20 years, and I still love what I'm doing. A big part of that is being able to create new things every day.
