i felt that with age it took me more and more time to feel that i understood something. At first i thought it was age, but whenever i compare with younger colleagues, i realize it's often that i have higher standards for what "understanding" means. Whenever you've had the experience of realizing how much more complex something that looked simple was, you start to look at every problem with much more care. That may makes me look like a a "slow" person or someone a bit thick, but then i often come up with interesting questions that makes everyone realize they didn't understand the problem as well as they thought.
