Everything depends on habit. Old people can do, of course, more or less well, what they have been doing all their lives; but try to teach them any new tricks, and the truth of the old adage will very soon show itself. Mr. Henry Hastings had done nothing but hunt all his days, and his record would seem to have been a good deal like that of Philippus Zaehdarm in that untranslatable epitaph which may be found in “Sartor Resartus.” Judged by its products, it was a very short life of a hundred useless twelve months.
It is something to have climbed the white summit, the Mont Blanc of fourscore. A small number only of mankind ever see their eightieth anniversary. I might go to the statistical tables of the annuity and life insurance offices for extended and exact information, but I prefer to take the facts which have impressed themselves upon me in my own career.
The class of 1829 at Harvard College, of which I am a member, graduated, according to the triennial, fifty-nine in number. It is sixty years, then, since that time; and as they were, on an average, about twenty years old, those who survive must have reached fourscore years. Of the fifty-nine graduates ten only are living, or were at the last accounts; one in six, very nearly. In the first ten years after graduation, our third decade, when we were between twenty and thirty years old, we lost three members,--about one in twenty; between the ages of thirty and forty, eight died,--one in seven of those the decade began with; from forty to fifty, only two,--or one in twenty-four; from fifty to sixty, eight,--or one in six; from sixty to seventy, fifteen,--or two out of every five; from seventy to eighty, twelve,--or one in two. The greatly increased mortality which began with our seventh decade went on steadily increasing. At sixty we come “within range of the rifle-pits,” to borrow an expression from my friend Weir Mitchell.
