I want to live until I decide to no longer live. I hope that scientists figure out how to do this. I have no faith that they will, but I have hope.
With religion you have "faith" that it is all as you "hope". I do not agree that they are the same.
I respect you decision to die and I respect the decision to live forever. The choice is not ours at the moment, but in the future I hope it will be so.
