I find airports to be the most impossible place to find decent food. Fruit is about it, but 6-8hrs of travel leaves me wanting for a bit more. So one time I picked up some ground beef on the way to the airport, got through security fine. I didn't want to draw attention so I got a large cup and put it in there, and ate in quick bites when no one was looking. I've also brought eggs and ate them quickly in the restroom. I guess a few guys saw, but whatever.
If I'm having a discussion about diet, I usually try and stress the problems with grains, preservatives, and processed food. I'll start talking raw when the person seems open minded. And then I'll usually mention sushi, oysters, eggs, rare steak and tartar to point out that it's really not as crazy as it sounds at first. But no matter what, I always point out that the biggest culprits are grains, preservatives, and processed food; and make mention of genetics and paleo-diet. I figure maybe they'll go look it up and move just a step closer to paleo.
Haha, then sometimes before I've ever mentioned any of this, and it's obvious the person is close minded, I'll recommend something 'crazy' like raw chicken as an antidote to their ailments, but never tell them about my diet.
I was in Walgreens the other day getting water for my car, got in line, and this lady in front of me looked terrible: overweight, sagging face, confused eyes. Under her right arm was a 12 pack of soda, and in her left was a basket full of sweet tarts, milk duds, and every type of candy-bar known to man. So she grabs a packet of cold medicine as a last item before checking out. I can't contain myself at this point; "Not feeling so good?" She replies, "I've heard this is great stuff for a cold," I simply said, "Oranges and honey." She informed me that did not work for her, and I left it at that. A few minutes later I passed her in the parking lot and said, "If you put life in the body, you will get life back from the body." She said "yeah I know." ... she had no idea.
