You might find this weird, but one of my worries is a big asteroid hitting earth. Weird? I know not a lot of people worries about it. what can you do, right? Of course nothing. So why worry about it? well, I am not really worried to the point that I don't go out of the house anymore or something. From time to time though, I do look at the sky and will wonder if anything up there that our 'experts' is missing and is now heading towards earth. I can remember one year( maybe this is why I worry) that a fairly big rock, that would create a big damage, passed our planet by a few thousand miles. That was the good news, the bad news? nobody sees it until it passed earth two days later! why? because it came from the direction of the sun!!!..well, it happened before, it could happen again, it's just a matter of time, right?
