A Fertile Mind

                  Image result for old couple in wheelchairs
I came across an article on the web discussing evolutionary biology. The focus of the article was on fertility. Seems Mother Nature has only one aim at all times, propagate the species. In short, life must keep on going and that means babies. We have all heard this before. It's nothing new but what was new was the theory on the end of fertility:

If Mother Nature is so obsessed with babies, then why do females, at least the human ones, have an and to their fertility.
We know this moment as menopause.

Well, according to the article, it takes some twenty years or so for a human to reach full maturity. The author cites athletic performance as proof. Athletes start their peak performance some time in their early twenties and that is the starting point of physical and mental maturity. If it takes twenty plus years from birth to adulthood, then the parent must be able to live that long to care for the child. 

No point having a baby in the last twenty years of your life as the baby would die when you die because you are not alive to take care of it. Therefore, female fertility ends some twenty years or so short of anticipated female life expectancy.

That's some theory, isn't it!

But, the article does not stop there. The article goes on to ask the question why does male fertility continue right up to the end of anticipated male life expectancy?

Before the answer is revealed, the article explains that males have a form of menopause, their fertility, sperm count, goes down. Much more significantly, males ability to achieve an erection goes down too. It's harder to impregnate a female if you can't get it up (my words), at least that's the story for human males.

Now for the answer to why male fertility continues until death. One word, mortality. Seems that males, the young ones in particular, tend to be aggressive, fearless, and fight each other to the death. We all know only too well the dumb behaviors of youthful males: drinking, drive by shootings, bungee jumping, a few wars, and so forth. 

So, Mother Nature decided to keep male fertility going, just in case, all the young males in their prime do dumb things and kill themselves off. The old guys can step up and fill in the gap so to speak.

All I can say is I am impressed with the ability of the human mind to come up with very creative and incredible rationalizations to questions no one asked.  

One more thing, don't believe everything you read on the web.

The Door Of Life - part one

Turning to look at her mom, baby Jessica said, “Mommy, why do you have a door on your forehead?” 

It was after lunch and Jessica sat on her mom's lap holding her picture book, Creatures of the Forest.

“Oh honey, nothing awful. It's so I can get my bad thoughts out of my head," replied her mom.

Jessica turned to her book and touched the face of a bear. “Mommy, how come daddy doesn't have a door on his forehead too?”

“Your father has a door by his heart to let love in.”

Jessica rubbed her hand along the page, petting the bear. "How come I don't have a door?"

"You will, sweetie. When you grow up, you get a door where you need it the most."

Turning to reach for her mom. "Can I touch your door?"

Her mom leaned her head back, "No Honey, only I can do that. It's not nice to touch other people's doors."

"Oh, okay." Jessica turned back to her book and turned the page to a picture of four robins perched on a tree branch. S…

Social Politics

I read in Google News that many states and cities in the USA are considering banning sugary drinks like soda. They claim that sugar is causing health problems and the government wants to save you from yourself. There are some other things that governments are doing, like requiring salt and fat warnings on restaurant menus. 

To some people, this is the nanny state. Others call it overreaching and others yet, creeping socialism.

Well, for the record, I think we already have a partial socialist state. It cannot be helped. Whenever the government steps in to help the citizens, you have socialism. 

Let's consider one of the biggest government programs there is in the United States, Medicare.

Medicare is a program of healthcare insurance. In short, the government collects money (taxes) and uses it to pay doctor and hospital bills for retired people. Whether the government does a good job or not is not the issue here.

Then, we ask the government to go one more step, to spend the money (taxe…

The Caped Crusader

Clarke was unusual for a caveman, he was a superhero. He could leap over tall buildings. 

His problem was that there were no tall buildings and would not be any for another ten thousand years. It was quite a dilemma for our superhero so he was reduced to leaping into tall trees. His current problem was that he had no superpowers to leap out of tall trees.

One day while climbing down from a tall tree, Clarke watched a squirrel leap from a tree. The squirrel spread its excess skin and floated to the ground. Eureka! problem solved. 

Clarke ran to the cave of his beloved girlfriend, Lois. After much description to Lois of the squirrel, Lois sewed him a scarf made from the lightest and softest bear hide. 

Clarke donned his new scarf around his neck and shoulders. He leaped into the nearest tall tree. He jumped from the tree, spread his scarf, and fell face first into the ground. 


Clarke sought out his friend Einstein. Clarke explained what he had seen of the squirrel, what he wanted to do,…
