As for me, it's not going to happen. I may not eat huge quantities of meat but I love to cook and eat a wide spectrum of dishes. I guess I get bored with eating the same old things, I like to mix things up. Heck, if I see someone's profile where they classify themselves as vegan, it is a deal breaker as far as I'm concerned. I'm one heck of a cook and too old to start totally trying to revamp my cooking and eating patterns now and I refuse to cook two separate meals.
A few months before my mother passed away at the age of 80, she was stressing out trying to understand what types of things she could or couldn't eat regarding the 'heart healthy diet' her doctor kept telling her she needed to be on. I finally sat down and told her that she had a choice (we always do). She could decide to approach her remaining life with either the aim of quality or quantity. If she was genuinely anxious to live as long as she humanly could, then we could print her out menus, recipes and shopping lists of what she needed and she'd have to work diligently to follow the recommendations. If on the other hand, she preferred to live out the remainder of her time, doing and enjoying the things that she had always done, then she could do so but must realize that she may or may not be with us as long. Although she was still somewhat fearful of dying, she chose the later and continued to cook what she liked and the way she always had.
Personally, I try to avoid much processed food with all the additives etc., as I enjoy cooking from scratch, by the healthiest means possible . That being said, people don't keep asking for my recipes because I cook with bean sprouts! Besides; while I may not have a death wish, I also have no great desire to make myself miserable just so I can stay down here longer. I'm looking forward to the day I get called home!
