I produced more code and put in more hours in my 20s and 30s. Looking back, a lot of that effort was spinning my wheels, not focused, and too biased to technology for the sake of itself. Now in my 50s I focus on business value, reducing costs and risks, seeing software as part of the business. I also spend more time mentoring younger programmers. It all feels like prime time, just different focus and rewards.
