I agree with BigC, and with all the other people joining in this thread and telling Knox213 about what a big risk this is.
It sounds like you've done a lot of thinking and I being a year younger than you have no right to tell you what to do. I think you're doing it for a noble cause.
But I certainly wouldn't do it. Yes, I *KNOW* that I am the biggest coward around. No need to elaborate on that.

But I'd rather work with animals when I get older, and being a female I wouldn't be able to join the army *anyway*, but even so.... People get killed every day on the battle field. Canada has the highest warfare mortality rate.... or something like that, similar, for sure. Idk. Yeah, but.... It's a big decision. ^^; Choose wisely, my friend.
