  • "Counting people tells some interesting things. Especially since computers enable us to extrapolate things into the future. Take this, for example: If the population of the earth were to increase at the present rate indefinitely, by AD 3530 the total mass of human flesh and blood would equal the mass of the earth: and by AD 6826, the total mass of human flesh and blood would equal the mass of the known universe."
