That's actually a really good question to get answered in my opinion. I haven't ever asked it before but since you pointed it out, it's great information to know. Otherwise, you'd continue sitting here thinking that things could get a lot worse.
You also showed something else that's very important, and that's asking the community. The community can ask as a personal library for us. I can't count the number of people here that have some form of knowledge on a subject.
Take care :)
