You could still stay at the edge of the flock and follow a zillion people who've "gone back to nature" ... but the nature of post-hunter-gatherer agriculture. Stick to growing plants and raising animals we're on very solid grounds WRT short term toxicity vs. "This wild stuff doesn't seem to be deadly" and then accidentally find out the conditions and dosages in which it turns out to be.

The flock itself has value; you don't have live with someone else, but as jusben1369 points out, if he'd so much as broken his leg falling down the steps of the bus he'd have ended up just as dead. Regular contact with a neighbor would have saved him, but he had no reserves and no margin for error.

I'm just pointing out that some risk is necessary and complete risk aversion can lead to undesirable outcomes. A lot of people here probably moved far from their home base to work at a startup for example. Some were exposed to completely new cultures and lost comforts of home because of it. If they did what their family or friends did they would have stayed home and not took the risk.

People from my home state think California is an awful place. I moved here for work and couldn't imagine living anywhere else--imagine if I'd of took their word.
