I was recently out in the back yard, clearing some wood. This also happened to be the first time this season that I had done any especially hard work with my hands. So I ended up with a handful of blisters and cramped hands. Definitly not something I would want to have to contend with in an actual survival situation. So I have incorporated keeping my hands in shape into my preparedness planning. This wouldn't have been a problem for me two years ago, when I was working construction, but now that most of my time is spent in front of a computer, it has become an issue. Figured I'd pass this realization along to the rest of you.
