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 feel like shoes are one of those things that no matter how conservative or how outrageous you get, a good pair of shoes is going to last you a lifetime.
