It seems that "equipped to survive" should most definitely include physical conditioning. While not nearly as romantic as preparing for an immediate survival situation, daily survival over the long-term includes lowering one's risk of heart disease, diabetes, cancer, etc., all of which include exercise and diet (or so the "experts" have conveyed). Really, what good is being equipped for a disaster if, at age 45, you drop dead of a heart attack because you had a real soft spot for bacon and your recliner?

I try to maintain a healthy level of activity (although it is currently time to ramp it up again). I'm 10 pounds over weight but working on it. I'm 37. The time of immortality is behind me. If I'm going to be equipped to survive, I need to take care of the ticker. I suspect it's even more important than having my PSK on me daily. Just food for thought.
