Well, we seem to be a pretty hardy bunch!
Maybe we ought to arrange a rendezvous location now, and all make our way there in the event of An Event.
I think I feel pretty confident that NT and I could survive in terms of food and drink and shelter and stuff if we were in medieval or stone age conditions, especially in a small community of like minded people. What I fear more in the the breakdown of modern 'civilisation' is the initial period of chaos, when the bullies take over, and use force to get the stuff they need. Chances are they'll only think short term (grab all the supplies in shops and warehouses and protect them with guns), but in the process, they could well do a lot of damage to those of us who just need to get through that time and settle in for the long run.
