and if something happened to your neighbors and friends? Maybe something you should consider, worst case senario. I don't think I would be willing to be counted on by friends if they could not contribute and did not know how to do it themselves. If you are injured or sick and need to have help, that is one thing. If you don't know how to fend for you and yours, what good are you to them or yourself? If you look at it as being the only person on earth left, you would not survive.
