Melody is not smoking, so smoking is bad and is one of, you know, probably the most, although it's not the most prevelant unhealthy behaviour anymore, at least in most countries. It's one of the worst in terms of almost every health outcome you can think of. And then I think there's two things that people don't really think about as much that probably are at least as important in terms of longevity. And the first of those would be social connectedness. So having a sense of social integration and, and that's measure in lots and lots of different ways. Sometimes it's about the strength of your personal relationships and your perception of the support that you received from those relationships, or the intimacy in those relationships are having a confidant. So that’s, that's one aspect at being engaged in the community around you in some way. And the other aspect is having a sense of purpose and sense that you're that there is something bigger than yourself and that you have.
