Many years ago I was a very lean vegetarian (who hadn't learned to like veggies all that much). I went through 6 weeks of Peace Corps aquaculture training eating at southern buffets every day, resisting most forms of protein. Then we went to Africa. Within months of eating the high carb, low veggie diet there I CRAVED meat. Not only meat, organ food. I could put away a huge plate of cooked meat, liver, kidney. I listen to my body. As Spring heads our way I start drinking tons of green smoothies: spinach, kale, yum!
Yeah, living longer for me is not a goal. Living healthier, yes. My friend's Mom is 93, just gave up her keys last year. Being 93 and active (cooking for the "seniors" at the center!) is great.
The world is like a mirror you see? smile and your friends smile back.
