Similar here, in my 40's and I must admit I also struggle with the management divide. However, I'm lucky that I work in a small company so I get to do a variety of work. I also have a lot of domain knowledge (medical imaging) which means I need to be engaged at a technical level. However, even when I'm working on strategic planning or market analysis I also manage to find a "reason" to write some little program to process data rather than just put it in Excel or hack up script to create a Gantt chart rather than use MS Project.

I guess you can take the boy out of coding, but you can't take the coding out of the boy!
