Well, I'm glad no one's given answers to Nemo's questions yet. The most helpful answer is to do the research yourself. Being a JW you have that certainty. When a question is brought up that has no answer, we start to worry if its the truth or not and the interesting thing is despite receiving a direct answer we do still get one.
"But what about this question...?"
"Oh, God will take care of it in his own time. Just wait on him."
There was no direct answer to your question, but you still did get one and you can move on with your wonderful life. So, even if you received answers to your questions, Nemo, who says those are right. Didn't you believe that the Society was correct before? Don't take people's word for it. I know how it is to want to be told something as though it is for a certainty. So, that you don't have to worry about life and death, the big mysteries of life. But, one thing that has helped me through this ordeal is that everyone goes through this, that is a part of life. If you want to be happy, than learn to lighten up, take a load off, and don't let these questions get you down. I truly wish the best to you, but don't give up. This is really just the beginning. And be happy with that. :)
