Which brings us to an interesting question... is the desire to live the product of addiction?
I think when the argument is taken out beyond 10K feet like this, it starts to break down. Self preservation instincts are about survival and need fulfillment, not addiction. Is my need to eat when I am hungry an addictive response? No. Is my desire to stop off an get a when I've already eaten enough for that time frame an addictive response? Maybe. That largely depends on your eating habits, but I think it still illustrates my point. The heroin addict doesn't need the drug to live (try telling them that), but they need it to quell the physical and mental addiction they've developed (willingly). I think its fallacy to say 'I am addicted to life, so that is why I eat/breathe/sleep.'
