I've been vegetarian for 20 years and can't imagine going back to being a meat eater. Although I changed my diet for ethical reasons, the health benefits have been great. Like Cataholic, I'm very active, work out with weights, cut down trees and drag boulders in my garden, etc. and don't feel any lack of energy or strength. If it wasn't for enjoying the occasional cake treat and a sprinkle of sheep's milk romano on my casseroles, I'd be vegan.
