Thank you for your concern. I tried vegetarianism long time ago. My daughter has been a vegetarian since she was 14 and she is now 51. When I tried vegetarianism I felt very weak and my energy left me. I tried all the tips for vegetarianism and protein alternative, but going without meat was impossible.. I have meat at least four times a week. Many times it is organic and I buy organic produce, always. The meat I eat comes locally sourced and I live in wisconsin. I'm still alive at 78. We all have to make choices that feel good or help us in any way. I m a blood type O positive. We are hunters from a long time ago. My daughter is not a blood type of any kind. She is an A or B I'm not sure. She takes after her father. She seemed to adapt to vegetarianism really easily. I found the book Eat Right For Your Type and I found it extremely helpful. That was a while back. But thank you for your reply it was very kind of you.
