I think a song that's got something to say. I'm not much on gimmicks. I never have been because they don't last. But I like a song that tells a story and has some meat to it, you know, that means something. ↗
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. ↗
