There are more difficult tasks

And you wonder how we'll just roll over you. If it gets tough, we'll break open a keg.

Aren't we all the same?

No. I'm sitting here watching a nearly brain-dead animal that three hours ago cried mercilessly for more food now sleep soundly a foot away from my computer. Any hungrier? If anything, more so now. So why now no noise? Same thing as always -- you are not as independent as you think. You are creatures of biology, as all of us are. WE know it. You don't.
