It's it, it's over, you're done for, what do you do?

We are all going to have to face death one day, there is no escaping it, so what should I do to prepare for that moment? Life is uncertain, it can give you more than you can handle, car wrecks, disease, and old age, to name just a few. What would you say to me, what would you do, if I was dieing right this moment and this was my last human contact? I’m dieing, as I write this, I’m facing the big mystery, what would you say to me? Positive, negative, words of wisdom to bring me comfort, or a slick good riddance.
