Sorry for calling you kooky Mark. I appreciate your contributions about music and gear. But I beg to differ about your dietary beliefs.
If Indians need to get their B12 from bugs, then wealthier Indians who benefit from better sanitation would be suffering from B12 deficiency. This is not the case. B12 is found in dairy.
The Silk soy milk I drink is fortified with B12, 50% of the USDA per serving.
I am happy that I have chosen a diet that is likely to prolong my life. And if I do live to a ripe old age, being vegetarian halves my risk of getting Alzheimers - a loathesome disease. See http://www.audarya-fellowship.com/showflat/cat/health/37376/2/collapsed/5/o/1.
