The survival of your species after your death is not a vested interest (a "special interest in protecting or promoting that which is to one's own personal advantage"). It affects you nil, by definition: you will be dead by then. What affects you is having children before you retire, because then you'll be fed and survive a lot more than otherwise. Evolution is a conclusion of that, not the other way around.
