How can i stick to my new found vegetarianism?

No, it doesn't make you live longer, this is a fallacy. It has been proven to maintain youth but not by a notable amount of time, only by a few years. I'd like to think if you don't balance lean meats with fruits, AND vegetables, your body will lack the energy, minerals, and vital vitamins it needs from the meats and dairy products to sustain your body to live longer.
