Read it through once

In India, the annual man-killings by snakes are as uniform, as regular, and as forecastable as are the tiger-average and the suicide-average. Anyone who bets that in India, in any three consecutive years the snakes will kill 49,500 persons, will win his bet; and anyone who bets that in India in any three consecutive years, the snakes will kill 53,500 persons, will lose his bet. In India the snakes kill 17,000 people a year; they hardly ever fall short of it; they as seldom exceed it. An insurance actuary could take the Indian census tables and the government's snake tables and tell you within sixpence how much it would be worth to insure a man against death by snake-bite there. If I had a dollar for every person killed per year in India, I would rather have it than any other property, as it is the only property in the world not subject to shrinkage.
