I have lived a self sufficient life for several years but picked up the intensity in the past 5 years or so. I'm not going to list anything here that lets anyone who might be sneakin' in the virtual back door to know specifics.
I will say that everything has been re-engineered to make it bigger, stronger, and most robust. Every person in my inner circle is ear to the ground, hand on the Bible and workin to be smarter. Every Action Plan, every checklist, and every item to-do has been duplicated, rehearsed, and re-invented to be more efficient, faster and more flexible. And oh yea, in the past 2 months we've focused on everything having to do with fallout shelters - that's an area I never much was concerned about before now.
I'm older than some of you. Age is no excuse. IMHO you're either part of the problem, part of the solution or part of the landscape. Yes, we all have health issues but there is SOMETHING that everyone can do to make themselves a worthwhile, contributing member of society now and in the future.
