. In Nepal it is even worse: all used Battery acid with heavy metal lead oxides and all the used acid from dying factories flow to the Bagmati and Bishnumati river and two days later it is in Tarai where the most fresh water fish come from. There was a disease called cancer even in stone age. It is not something new. Majority of people are living much longer now than before.Vegetarian does not live longer than smokers or non-vegeterain.Sai Baba is vegeterian , he has big health problems now.I do not think he will be 100 years old. I do not think about heavy metal when my Beef Barbeque or my fish is right in front of me at the table. I just enjoy my food. If you really start analysing, there won´t be anything left that is edible? .
