because no man will give for an annuity upon the life of another, whose age and state of health are nearly the same with his own, the same price which he would give for one upon his own.

Context

“But if, by advancing their money, they were to purchase, instead of perpetual annuities, annuities for lives only, whether their own or those of other people, they would not always be so likely to sell them with a profit. Annuities upon their own lives they would always sell with loss; because no man will give for an annuity upon the life of another, whose age and state of health are nearly the same with his own, the same price which he would give for one upon his own. An annuity upon the life of a third person, indeed, is, no doubt, of equal value to the buyer and the seller; but its real value begins to diminish from the moment it is granted, and continues to do so, more and more, as long as it subsists.” source
