The link above will take you to a recent column that explains that the children of "older" men are more likely to suffer particular ailments vs. the children of "younger" men. Where is this line drawn? About the age of 40, and this is my age. The wife and I are working on our first child nonetheless.
My father had three of his five children after he turned 40, and we "three little ones" are doing fine. Granted, one of us has decided to "play for the other team," but other than that, we're doing "fine." This story is pap! All it is trying to do is to influence women to look for the seed supplied by younger men. So, all you older men out there, may want to stick to the media and either turn it off or change-the-channel to an outlet that doesn't buy into this pap.
The issue with "utilizing" younger men is that the women who do this are going to be increasing their chances of having girls, and this is how it all boils down. This story is the product of a "fem-nazi" media. You will do as they say or suffer the consequences. Some women are predisposed, physiologically, to produce girls and this is the work of the Good Lord on his own. No issue with THAT. The OTHER issue is the seed. To produce boys, the seed used to produce the boy is a LOT older than the seed that produces the girls.
Younger men are predisposed to "tap the keg" on their own and keep their "stock" of seed relatively new. This leads them to be more likely to conceive girls with their seed. Older men are a LOT more mature than this and less likely to "tap the keg" on their own.
This is why Henry VIII never had a boy! He couldn't keep his "keg" full of anything long enough to make it more likely that he would conceive a boy! He had someone tapping it as often as he could "convince" someone to tap it for him! *laughter* When you're the King, you can find someone to do this for you! You're the King, after all.
So, what these Gomers in the media are trying to do is to convince women that they need to get their seed from younger men, but this comes with a caveat, ladies. You need to make sure that the product you're getting is aged enough. Otherwise, you are likely to increase your chances of having a girl as a child.
Granted, there's nothing wrong with girls. They are wonderful. Don't get me wrong here. The niece whom my wife brought to the relationship is a DOLL.
