These kind of statistics really mean nothing, because they don't
factor out common life-style characteristics of particular groups. For
examaple (and without meaning to trash national icons), I have heard
that steroid use in the off-season is spreading among football
players. How does that effect life-span? Likewise, do football players
party hardy, more often, later into life, than mere mortals? Finally,
football in particular is a fairly "brutal" sport. Would you be
surprised to find that champion prizefighters have an average lifespan
of only mid-forties? No? Then you shouldn't be surprised that football
players have shorter life-spans than average. (BTW, the "mid-forties"
lifespan for prizefighters is hypothetical, to get my point across; I
have no idea what the real number is.)
As for marathon runners: by any chance do they tend to stop running at
55-60? Just the first question that comes to mind, but I find you
really need to "study the study" to determine if the conclusions can
even begin to be considered valid.
