I tried the paleo diet, which is the caveman diet - lots of meat. And I tried the calorie restriction diet: The idea is that if you eat very, very little - if you're on the verge of starvation, you will live a very long time, whether or not you want to, of course.
I distanced myself, relatively, from my parents for a year or so in my late twenties. It was necessary for me to feel my autonomy. Other than that brief gap, we have always been a very close family.
