The truth is the only thing you said that I don't agree with is your first sentence.

"You only get one go around on this big blue marble"

Having had my own near death experience I don't know that we only get one go around, though I would agree with the rest of what you said. The truth is we don't know how many shots we get, but however many there are it would be prudent to live them all out. lol Nice post.
