Excellent comments light blue. I agree we fear the unknown.
Picture yourself on a roller coaster (which you know ends up well) and you are making the slow incline at the beginning of the ride. Any fear?
You get to the top and you get that terrible feeling in your stomach!!!! Then down you go and it is the most awesome feeling as you know you are going to make it.
And what do you do when the ride is over?
You guessed it .....Let's do it again!!!!!!!
