That which doesn't kill us makes us stronger.
Some of my sims do grow all of their own food and sell the surplus at markets in various ways. But whether talking about sims or people, there really isn't much point in trying to figure out how to grow all of our own food and harvest our own eggs when choosing to live in a densely populated urban center with millions of others, or in a suburban tract with maybe just enough land for a rosebush and a single tomato plant. Especially when the municipal water supply is under suspicion, the government is spying on us through our webcams, and we are constantly being irradiated by cell phone and wifi signals buzzing all around us (tightens up tin-foil hat a bit).
Can't help but feel the discussion is veering off-course a little now, even though I'm clearly contributing to that. ;)
