Oh, heh, I didn't eat all of those at once! It does take some persistence to peel them, though.
Isn't it interesting how, when we learned about mechanics, we thought how much like a clock the body was? And then when we learned about electricity, how like a battery, and when we learned about computers, suddenly the brain was like a computer. I wonder what our next scientific breakthrough will turn us into?
It's so true that things compare so completely. It's kind of a wonder that discoveries aren't more intuitive and faster but then - hindsight...
