I have always considered a reasonable level of physical fitness to be an important part of my overall readiness for the unexpected.

I'm not much of a runner (trick knee) but I am a pretty good walker (slow and steady, but I can jog short bursts in hiking boots).

To my mind, mobility is a critical part of my "kit." My minimum requirement is to be able to walk/run five miles in just over an hour without dropping dead of a heart attack, or walk ten miles in under three hours at an efficient pace. This is paired with always having the footwear, clothing, and basic gear to do so at any time.

For me, fitness contributes in many ways:
- helps prevent injuries when dealing with the unexpected
- contributes to coordination, balance, and flexibility
- helps a lot in maintaining a positive mental attitude and mental alertness/concentration
- gives me increased confidence that I can assess and handle situations in a hands-on way (this is a gut-level thing; hard to describe but it's real for me)
