I have just gone opposite route. I turn 42 this year and just started job in a more technical role having spent 8 years in management. I moved into management because I was a very good developer. I don't think I was a bad manager, my teams did well and won awards. However, I couldn't stomach the endless meetings and admin tasks that came with being a manager. I carried on reading Hacker News trying to keep up with the latest trends instead of moving on to reading management and finance sites. In the end, despite the ageism stories abound I decided to go back to technology. Its been 3 weeks into the new job. I am appreciating the time I have to immerse myself in the technology. Good luck with your quest.
