I'm not up-to-date on the physiological traits of the woman of today but I think they stopped making or teaching this version about the turn of the decade on or about 1939 - 1940 !
The room was full of pregnant women with their husbands.
The instructor said, "Ladies, remember that exercise is good for you.
Walking is especially beneficial.
It strengthens the pelvic muscles and will make delivery that much easier.
Just pace yourself, make plenty of stops and try to stay on a soft surface
like grass or a path."
"Gentlemen, remember -- you're in this together, it wouldn't hurt you to go walking with her.
In fact, that shared experience would be good for you both."
The room suddenly became very quiet as the men absorbed this information.
After a few moments a man, at the back of the room, slowly raised his hand.
"Yes?" said the instructor.
"I was just wondering if it would be all right if she carries a golf bag while we walk?"
Brings a tear to your eye doesn't it?
This kind of sensitivity just can't be taught.
