I was thinking about exercise yesterday.  And for some reason started thinking about my Dad.  I don't think he ever did any formal exercise.  No running, walking, weights, jumping jacks... maybe back when he was a schoolboy, but probably not after.  He was always fairly fit, and never overweight, often leaning toward being underweight.  He just lived a fairly active lifestyle.  He was always outside working on cars or equipment during his time off. He was an electrician, so it wasn't a super strenuous job keeping him fit. (more active than a desk job, but still not like a loading dock!)  Just one of those things that dawned on me and made me think :)
