Now, really, how early is too early?

The good people at The Spark have provided the Death Test. Accordingly, I expect to shuffle off this mortal coil on February 11, 2048, just shy of my 78th birthday. I’m reasonably confortable with this; it’s the 9% chance that the cause of death will be “electrolysis” that bothers me, not to mention the 5% chance of “wild animal mauling.”
