Huh, I seem to be getting something way different from this comic than most people here...
I'm seing knowledge being transferred, and as the number of sources and amount of information increases, it gets harder to figure out how everything interconnects and how it all fits together. But as you get older, you get more experience and start to see how things fit together and the world makes more sense. In the end the jumbled information you've received through your life makes more sense to you, and you transfer the new sum of information on to someone.
