I wanted to counter this with the fact that you and me are both still alive, so the rate is only approaching 100%, but probably never quite there.
Then I did a safety google, and got to learn that fatality rate apparently doesn't care about the time until death. So as long as I don't assume I'm immortal, your fact still holds true.
But then I remembered that some jellyfish and sponges are considered to be be more or less immortal.
Which raises the question: do we count beings which will most probably die out due to the expansion of our own sun as part of that 100% rate?
