I like to mark it in my spreadsheet when I do 45 minutes of cardio, not that anyone cares about this "achievement", and I do not expect recognition... being healthy later in life is a nice goal, but it is awfully vague and abstract, kind of like being a good diver... collecting check-marks on my spreadsheet is more tangible, and I can trick my lizard brain to desire a weekly quota of those checkmarks. In the end, the result is the same.
