Let's say we're dealing with a trooper who's sitting and driving a tank all day long, and he's cramped in small quarters, bouncing around in a tank all day with poor suspension and banging his head on this and that while wearing a helmet, etc. When he finally comes out and has a car accident, how do you determine if it's because he's been driving around in the tank that caused his osteoarthritis, or it's the fact of the car accident that caused the osteoarthritis?
