Thanks Flatlander-- i never made the connection.. (d'oh!)
but getting back to Ant-- and Ant question.. ant mentions Political and social returns.. and for this i would go back to the idion about a pendulums swing.. what is decent changes.. from ankle lenght skirts for women ot hot pants.. from low cut, bosum exposing blouses, to high necked ones.. in the 50's, premarital sex was a social No No, in the 60's we had a sexual revolutions.. in many way now, we are back to much more conservative sexual mores.. the change in behaviour is driven by disease. but it doesn't matter.
what matters is casual "sleeping around" somthing that was ok, in late 60's and early 70's is not ok now.
in the 50's you might have been labeled a slut, especially if you were a woman and now you are a health hazzard.. but no matter the reasons, chasity is on the rise.. the pendulum swings.
