G'day Amy,

A good question ... one that has bothered me - without any good answer - some some time.

It does, however, remind me of a cartoon by an ascerbic Australian cartoonist:

A man declares to a woman: "When I saw you across the room, my heart went 'Boom'!" ... and she replies" "Well, if you think I'm going to marry a man with a congenital heart defect - think again!"

(Er .. I do hope some has a better explanation for you.)

Regards,

Bob Bolton
