"Maybe it's just a bit of lifter tick, maybe a rocker going bad. No. It's much worse than that. You live each day in fear, gingerly moving, slowly, but you get by. For now. But you never know what day that knock will turn into a hole blown right through your mid section."
In a way I want to get the shirt, but I don't want to keep reminding myself of this when I drive the car!!!
