I'm a cancer survivor. I chose not to go the science route because it could not guarentee that they can fight the cancer and win. Instead I chose to have the tumer removed and practice yoga, healthy eating, prayer, meditation, tai chi and qi gong. I've been cancer free for 5 years this month. The scientist were screaming at me that if I don't take their scientific treatments that I would die and be dead in 5 years. But still they had no proof that it would cure the cancer and I would live longer than 5 years.
There is so much the mind can do that we could never really know and understand and test everything scientifically. Science can learn about it but it can't know everything about it.
I believe that science can be a form of religion. It can be pushed down someones throat just like any religion. And anyone that doesn't believe in the science is judged as irrational.
