Listen to your body
/Forgiveness - Talk about how resentment and negativity affect our bodies and how letting go of that can positively affect our health. Perhaps there are some case studies we can pull from. I think Louise Hay would have some examples of healing through forgiveness.
Surrender - Maybe something about being in the present moment, letting go, and the positive mental/physical benefits? Perhaps this could be another plug for meditation.
Attitude - I know this is self-help 101, but I still think a lot of people with health issues are hung up on thinking negatively all the time about their problems. Even seeking attention for them. Perhaps a blog on the importance of positive thoughts and attitudes would be nice. I'm sure there are short case studies we can reference as well.
