I'm with you, I'm rounding 40 myself, and was not happy for the brief couple years of management.
When filling out a 'secret question' for some site, it ask what your ideal job would be. I didn't even blink, it was: developer.
Do I want to be doing this when I'm 50, hells yea.
If I had trillions of dollars, I would still code. It's who I am, it's what makes me happy. If you don't think you'll like development at 50, then you may have picked the wrong career.
