Also, the whole "once it happens to someone, they care" applies to pretty much anything. Find someone who invests a lot of their time speaking in public for any cause you can imagine. Someone who talks to audiences about the perils of alcohol, drugs, any cancer or disease - basically anything that is harmful/dangerous/deadly. How many of them do you think ever gave a second thought to their cause, before it affected their lives personally (themselves, a family member, or close friend)? Practically none of them. People generally don't care about the consequences of anything until they've been slapped in the face by it.
