What If

I did a calculation about how much money not smoking would end up saving me over the next 20 years and it turns out it will be enough to pay off my mortgage. How cool is that? Along with some money recently earned I may not have to wait 20 years to pay it off too. What that also started was a question about if I still needed to spend the hundreds of dollars a month on home insurance. A knee-jerk reaction might be no, but then again, just because there's no mortgage to pay off, what would replace the house if something happened? What would pay the bills if someone got hurt on our property? Those things don't happen every day now, and wouldn't happen every day if the house was paid off, but they could still happen and without insurance we'd either have no place to live, or lose the house and maybe even more.
