E, I pray when I am 70 I am able to hike in the mountains and work out. I meant no disrespect in my previous post. I do however disagree with what you believe and I think you are the kind of person who it really doesn't matter the way you eat you would still be healthy. Kind of like someone who smokes their whole life and lives to 100. The problem is the average person can't smoke and live to 100. I've seen with my own eyes way too many examples of people getting away from grains and processed crap and eating paleoish and doing tremendously better.
