Why not apply behavioral economics to s**? C., an MR reader, writes to me:
The theory, put plainly by me, is that the female (or male) partner in a couple is never cuter or more loved than just before fertilization, so why fertilize as much as we do? Why not once a fortnight or so (with sex without satiation 2x a day in between)?
I am told this will preserve true love forever. Here is a related article. Here is a related book, which I have yet to read. Here is the main Google blast on the topic.
How many of you read this and then revise downwards how much you think you desire true love forever?
