>>immortal or breed and have kids
Well, I've been sorta agonizing over that bit. My initial thought was that the two of you would be immortal, but sterile. However, I am thinking that perhaps I would provide you with the option to make that choice, so the shiny box now has a toggle switch to accompany the button -- switch the toggle to "immortal" and you and your perfect woman are cured of aging (but not invulnerable, so please do be careful), yet unable to bear children. Switch it to "mortal", and you are both perfectly healthy 18-year olds, in fine form to breed to your heart's content, but also with a normal aging cycle.
BTW, just to show you what a great demi-god I really am, the shiny box has no expiration date, works only for you (non-transferrable), and the deal comes with no strings attached. Accept the box, and the choice remains yours until you choose or pass on.
So, do you push the button, accept the box and save the button-pushing decision for later, or simply refuse the offer altogether?
