There's a categorical difference. I live for all the things life is about, but for some causes like my children and loved ones I'd rather die than keep on living. Not for everyone I love of course, but for my children for sure. So maybe the question is better posed as what would I die for? Obviously there are the physical needs, where a constant lack has the consequence of dying. I live to eat, drink, sleep, clean. To care for shelter and health. To gather resources, which is just money in our modern society. Apart from that, I also live for my children and loved ones. Are there any other things I'd die even though it wouldn't kill me like dehydration? Politicsl ideals come to mind, but thankfully these scenarios are so abstract, that I don't know how I'd actually react.
