Join the army? Stay home?

Back then, people joined the army to represent America, to fight for Americans, and to have new adventures, which is kind of the same as it is today.  I think if a person wants to join the military, the risk of losing their life should not hinder them, since they want to.  However, for me, personally I would like the promise of living, which is obviously not promise-able, especially during the middle of a war.  In order to join the Civil War, for me, I think all I would need is a strong motivational idea inscribed in my mind, since I like to stick up for my beliefs.  If I was a soldier, I think the hardest part might be struggling to survive everyday, whether it's walking a great distance or fighting for hours, OR it could also be the risk of death every waking moment.  Being separated from my family for long periods of time; I think I would be able to handle that, as long as I have friends in the army and I am able to keep in touch with my family, at least by mail.  Also, as the time goes on, I think I would appreciate the physical training, and it will also help me keep in shape :)  So basically, I think joining the army is a difficult decision, however the choice will be chosen depending on the person and his/her view points.
