At the end, there may well be progeny. But you wonder if Roger had this kind of self-concept problem, how did he have enough libido to attract a taller wife and marry anyway? People hadn't become particularly important to him.
There is also mention of an odd cream that is applied to the skin under clothes (maybe the chest) with nanotransmitters (maybe with carbon nanotubes?). Maybe this could be used as a kind of Holter device for heart patients. If this really exists, it offers real ideas for future movie plots.
