Nope! Don't Wanna Think About It!

Pssst.  Can we talk? I don't usually just scab off someone's blog and use as mine.  But in this case I thought it was interesting enough to do just that.  I know we don't like thinking about our parents having sex but I came across a fascinating article that puts us being here in perspective.  It was written by Peter Vidani who is author of the Scientific Philosophy and Philosophical Science blog.  His blog is one of my favorites.  Mike


And good thing too, since it wasn’t just any sex—it was the sex that led to you. There was a moment, a fraction of a second, where one single sperm that happened to be the carrier of half your genetic code, beat out, in a photo finish, nearly 300 million competitors. That would be like entering a foot race with the entire population of the United States—and winning. If that tight race had played out even slightly otherwise, if a different sperm had successfully infiltrated that ovum wall, well, you could bet your bottom dollar that it wouldn’t be you sitting here reading these words. You wouldn’t even be alive. Your entire existence, everything you are, is utterly contingent on the precise moment your father ejaculated. That one sperm, that single, creepy, wriggling little tadpole, united with your mother’s egg and crafted the perfect recipe for a human being later known as you. What serendipitous timing! What necessary timing!
But hold up, that’s not the whole story. It’s not just that one act of successful intercourse that matters. That same exact scenario occurred—had to occur—between your grandparents, and your great grandparents, and your great great grandparents, and your great great great grandparents… And so on, stretching all the way back—over 3 billion years—to the beginning of life on this here blue marble. Every relevant relative of yours was able to survive just long enough to reproduce (or replicate) and continue on its legacy. You are that legacy. And, it’s important to note, this is on a planet where over 99% of all the species that have ever existed are now extinct (meaning they didn’t share your luck). If ancestry.com could map this out, you would see a lineage consisting of hundreds of millions of your direct ancestors all having successfully reproduced, all at the exact millisecond required to pass on the exact combination of DNA that would lead exactly to you.
So next time you run into some bad luck—perhaps a burnt soufflé or a clogged toilet or another traffic jam or losing lottery ticket—just take a moment to think about your parents having sex. And remember all of the lotteries you’ve already won.

Flashback Friday

Class, Or Lack Thereof The Dwight Vice gravestone in Oquawka, Illinois. I bring this old chestnut out every so often just to remind me that class is classless.  Dwight Vice was killed in his home near Oquawka in 2001.  It was one of those things that can generate crime:  two guys thought Dwight had a lot of money stashed at home because of his pot-selling sideline to supplement his fishing job.   Not really one of those big drug deals gone-bad things.  Marijuana was, according to the trial, about the only stuff Dwight sold.   But these two guys barge into the house and killed Dwight and attempted to kill his 11 year old kid, Darryl, before they took off with what money they could find.   His son, now 23, was stabbed in the back and left for dead.  He survived and is wheelchair bound and has undergone several surgeries to repair his wounds.  He will be paralyzed for life.   None of this is pleasant.  Reading the f...

Florida Air Museum - Part 3

Welcome back to a pretty neat tour of the Florida Air Museum in Lakeland Florida.  There's a lot to see and a couple of the old Geezer Gold Wing guys are already sitting down instead of walking around looking at the exhibits. That's John who is wore out and making a call to his wife.  In all honesty, John was pretty well bushed before the ride.  He told me his daughter's family was down from one of the Carolina's with the grand kids and he must have played with them too much.   He's about to take off on his own and head for home, but he's going to miss a couple of neat things out on Hangar A.   But, before we walk over there, we have lots yet to see here.  If you saw The Aviator with Leonardo DiCaprio playing Howard Hughes, you'll remember that he went up in a plane during the filming of one of his movies to prove a point about flying.  He crashed trying to execute a roll and this is a picture of the plane he crashed.  No...

Summer Swim

It's Monday and the start of another work week.  Except for me.  I have the week off because the parents of my daycare charges are taking the week off, too. This is one of those wordless posts I love on Mondays so I can put my laziness in full view of loyal readers.  These pics need no words.  Why muddy the waters?   They were taken at the pool at Sinkhole Estates aka Death Valley.  The nice thing about this pool is it is heated in winter.  If one must find positives in one's situation, I suppose that is one.  But, please, no more.
