Nonya ,thanks for the prompt reply. But how our ancestors were able to lead a healthy life & they were quite active even at their ripe age.i had seen my grandmother rising early & doing cooking at the age o 70+. The cooking is done by her for the entire family.My ma & chitti after taking care of children will take bath & enter the kitchen. They will do everything after that.The children were not so pampered as in these days.In the evenings so many dosas to be prepared. Unannounced guests will come.So even now if i think of them only their working in the kitchen will come to my mind.Sometime my mothers reading books in the late hours of night.But i had never seen them unpleasant while doing the domestic core.That had added positive energy to the food. May be all the negative effects nullified. The Eeeya Chombu rasam pots are meant for preparing rasam only in most of the households. Were they not aware of its side effects ? Whatever we do , the destiny can't be changed. We takes so many precautions to prevent BP,Sugar etc.Here comes the Devil- Cancer unawares & non diagnosed fora long time. Mostly it is identified in Stage 3 or 4 only. No symptoms at the same time so many minor problems which no one will immediately associate with cancer.Even in my case just God helped me to note the reddish color urine which would have been simply ignored as due to heat as there was abnormal hot climate in Chennai. I had never drink water bottles at a time in my life time. How can one expect that it is a symptom of cancer in a hot climate ? But as u said Yoga & pranayam are the best medicines in this modern world where we have to live with modern gadgets , Cook in toxic metals, radiation based stoves , external air pollution , internal job & domestic stresses etc.Also a Good heart devoid of negative feelings, some charities & faith in God /Guru will ,if not prevent the effects of our past prarptha Karmas but equip us with tremendous mental,spiritual strength to face & bear any thing.
