Too much "can do" can do you in

When I was a student at the Naval Diving and Salvage Training Center (NDSTC aka The Dive School), one of the Diving Medical Techs/Corpsman had a saying.  He would often say "Too much 'Can do' can do you in."  You see, "Can Do" was one of the motivational sayings we would use, and his point was being too "can do" at the wrong time could have very serious complications when you or your dive buddy's life depended on your physical and mental condition.  Did he mean we weren't to push ourselves?  No-while he didn't look the most imposing physically he could PT just as hard as any other instructor and his workouts were no joke.  But knowing ourselves and our condition became a reinforced instructional point as we progressed to being Navy Divers and Navy Diving Officers.

Fast forward over 20 years, and we're both long retired from the Navy.  But his words rang true again yesterday as I did a full day of chores for the first time since my back spasm I've already written about.  One task even involved shipping a large heavy box-what contributed to the back spasm in the first place!  So throughout the day I was conscious of when my posture started slipping-like raking/sweeping up leaves bent at the waist or bending awkwardly while working on my motorcycle.  The back seemed to hold up pretty well and I'm not too sore today.  Just the usual age related stuff mainly, so hopefully I wasn't too "Can Do" on my Honey-Do list!  Oh yeah, I also need to book a whole bunch of hours of household tasks type work on the Presidential Fitness Challenge.
