If we observe our human body, many of the body activities are controlled by the autonomous nervous system that takes care of the body without our awareness or interference. This is the miracle of body intelligence.
Deepak Chopra, a quantum biologist who gave a new paradigm to body-mind connection, said that the body is a quantum mechanical device and that it is subject to the laws of quantum physics, not Newtonian physics. In 1986, he changed the way many of us looked at our mind and how the body handles the rejuvenation process. The older wisdom had pegged it at 7 years while Deepak Chopra revised it to one year (approximately 98% totally renewed).
Based on the estimates of quantum biology, you have a brand new stomach lining every 4 days, new skin every 30 days, a new liver in 6 weeks, even the skeleton is replaced every three months. Within one year, almost 98% of our body is new! Such a revelation fundamentally changes the way we assist people in the healing themselves and others.
