Don’t have much time today for writing, so let me quote Mike Clayton and give you a link to his physical preparedness website:
“Physical preparation is the subject we think of first when we look at the days ahead. We may think of food, water and shelter first, and though it may be important, it is last on our list. We can remain alive 3 minutes without air, three hours without shelter, three days without water and three weeks without food, but without God’s presence in our lives moment by moment, we are but dead men walking! Though much of this web site is devoted to physical preparation, please keep in mind it is not to become our focus or our fear.”
“For God has not given us the spirit of fear, but of power love and a sound mind.” 2Tim. 1:7
Visit Mike’s Torah is Life website for lots of great physical preparedness information.
