Missionaries-God love em. These honest hearted people doing everything they can do to help these poor people gain spiritual wealth for if you have God, who really cares if you don't have running water. Get God in your life and everything else is trivial say like malaria or having little food-no problem-you've got God.
I'm not so sure that all the dub missionaries have it that rough. From what I've seen, they get the hook up when they go to a country. One couple from my hall, just a year ago, that was doing construction and missionary work in Zimbabwe pretty much had all expenses paid for by the society. When they got there, they had their own brand new Land Rover and everything else that they could want including housing. However, they came back to the states because the wife did not like the hot weather and being on the road. Basically, her husband is a real stict dub who has been pioneering like since he was like 15 while she is not quite that zealous. From what I saw of their pictures, doing the missionary work was hard due to the environment, but most if not all material things were provided. Thus, if you like life on the road and not having a real job, I think it could be a lot of fun if you were really helping people.
The only bad thing I know about missionary work is that in the past the society has been slow about pulling international missionaries when war would break out in these countries. You know if you waited too long to leave if you are being rescued by the marines. Thus, I have heard the society has had a cavalier attitude towards the safety of its missionaries in times past, not sure if this is still true. I wonder if there are some dub missionaries freaking out in Haiti right now.
