I'am 52 and like you I realised that I want to stay with the technical stuff, just keep up with the technology and keep learning. I just love to find solutions to technical problems.

I also struck me that there aren't many persons around in their 50s-60s working striktly with software-/database development.

Then I realised why those people are so rare that you do not see a lot of them. First of all, they did theirs studies in computer engineering at a period where you programmed using paper card with holes in. It was a subject among others.

Then with the years a good part of these few students went over to administrative tasks. Well, that's my explanation. 😉
