This was a good talk. Inspiring. But at the same time I believe it needs to be taken into consideration the biological and spiritual aspects of life; nature isattempting an ultimate homeostasis. We humans are but apples on the earth-tree. I too have had a good friend diagnosed with cancer, and I have deep sympathy for all who have been afflicted along with loved ones. We cannot 'fight' nature because we do not see the big picture, all we can do is attempt to understand and work with her.
