Although it is a widely held belief that human beings are
mortal, the relevant statistics do not, in fact, support this
theory. Of all humans ever born, one-third were prehistoric,
one-third lived since history began and one-third are still alive.
Consequently, mortaility has only occurred in two cases out of
three, a statistic that by no means suggests that it will always be
true. So it appears that there is no significant evidence that any
of us will ever die.
