We're all guilty of ignoring the warning signs at some point.

I used to cruise around town with the dashboard in my car lit up like a Christmas tree. The car would be loudly knocking and clunking, and I'd just turn up the radio. My friends would say, "You should really get that checked out." I would shrug, "Nah, I'm sure it's fine." A few weeks later, I'd be shocked when I was stranded on the side of the road. Wow, that came out of nowhere!
