What are you doing today to live more healthfully?

Personally, I am trying to increase my activity level. No, not trying...doing. (I can try at something for ever, just need to do it.) Talked to my DH yesterday and decided I will join a gym this weekend. Plus I walked 2.5 miles yesterday and have already walked .5 mile today. I am teaching summer school which is 5 hours of classrrom time with a 10 minute break. So I am breaking up the 2 sessions with a 1/2 mile walk for me (and the kids). Makes it much more do-able for them and makes me walk. Then I can do another 1-2 miles during my lunch time after they leave and before I start the grading and planning.
