A recent New York Times Article: "How Exercising Keeps Your Cells Young" explains the connection between exercise and keeping the cells in our body healthy. It's hard to motivate ourselves to exercise - our doctors all tell us we should, and studies show that regular exercise can increase cancer survival by 50%... we KNOW we should.
But it's hard when we are tired, and life is so overwhelming.
Maybe if we imagine EVERY SINGLE CELL in our body getting stronger, with every stretch, with every stride, we are strengthening every cell and protecting it against cancer. That seems worth 30 minutes a day or even worth doing more today than you did yesterday. Any movement is improvement!
Think of it this way - it's cheaper, and a LOT less painful than chemo.
