I'm a person who went from an active life to a life where I'm sitting a desk for half of it. This was wholly based on a job change. More responsibility and stress with way less physical activity. In the past I've not had to worry about putting time aside for exercise, as my job always took care of that. Now, I'm having to learn to change my lifestyle to fit in with my job. I'm using FatSecret as Breaking habits and trying to make new ones… its always challenging.
