The number one survival tool you have is your mind, which will direct your body to do what you need to do to survive IF your body is up to the challenge.

That team - mind & body - only works if you excercise BOTH.

If you're too fat to run, to weak to climb, or too medicated to think clearly, then there's a good chance you'll die in a serious emergency situation. On 9/11 there were people who DIED for no other reason than they got too tired to make it down the stairs before the buildings collapsed. They sat, sweaty and puffing on the stairs and the buildings came down on them. Imagine that.

I have learned from the fire service that you can't say "adrenaline will get me through a real emergency" because it won't. I've been in enough real emergency situations with the fire department, and I've been in realistic live fire training exercises, and in both situations, I learned that you need sustained, aerobic fitness to be of any real use in an emergency situation.

When the time comes and you ARE carrying a backpack full of 80 lbs. of crap you think you "need" to survive make sure your mind isn't preocupied with your body asking for the next place to sit.

And that's what I think.
