I'm not suggesting it's definitively wrong based on my anecdote, I am just speculating that it might not be true and that it's hard to avoid injuries in life requiring MRI. Do you actually have discussions around medical issues affecting you or the people you know? I do, quite often. What is their demographic? I said over 35, which is the demographic I associate with; these people typically have a slew of injuries and medical problems accumulated over the decades, making it more likely for them to having used an MRI machine.
