Thanks for your comments. I think you are 100% right, we have to pave our own path to recovery. I agree cleansing, diet and our own attitude all have a role to play and yes i agree it is possible to regain some of our old vitality.
You should also look at Ayurveda, this is an ancient (about 2000yrs) old art of healing which comes from India. Here we not only look at herbs & cleansing, but also Yoga and spirituality. Ultimately if we can make our instruments (i.e. body) work right, then we will get closer to God and get to know him better.
Thank you for your comments.
