One of my mentors has described his life this way:
"when I was younger, I was learning 90% of the time and teaching 10%; as I've gotten older, wiser, and more knowledgeable, I have slowly made the transition to teaching 90% and learning 10% of the time"
When you are very knowledgeable, there isn't as much you can learn, but there will always be something.
