Yeah, from my human perspective, that's really weird.

It doesn't matter that much for humans. I mean, it's not nearly as important that we be able to survive on our own, because we haven't had to do that - at least in a lot of parts of the world - for hundreds of years. So there's no shame for us in depending on things.

...actually, we think the survivalist types with hunting rifles and bunkers out in the woods who could probably actually survive on their own are kinda crazy.
