I have practically no sample size but my own father shifted into more project management into his 60s and he's as in demand as ever running a team of 10-12 secs.
And I've personally hired a developer in his 60s for a startup. He was retired but just loves to keep programming and so took up some work with us. He seems to be in reasonably high demand as another company has been trying to hire him in the last month too.
