Things I Learned at School Today

This education stuff is fascinating. Even though 85% of the people at my school are morons.

Today in my developmental psych class we watched a video (watching a video on the first day of actual class... is that a copout?) about conception and sex and birth. It was a typical school video in its sterility, but I couldn't believe how they'd captured the clips that make up the film. They filmed an ejaculation from INSIDE the body, so you could see all the man spunk shoot at the woman's cervix. Then they zoomed in ridiculously close to the fallopian tube lining and on sperm with gimpy necks. It was incredible.

The big takeaway for me was that sperm have it rough. They are like little soldiers put in impossible situations, and yet somehow, babies are born all the time. For instance, when the sperm is in the man's body, it's dangling in a sack in his hot crotch trying not to cook to death. Then, when he leaves the hot sack, he and millions of his buddies have to swim up the littlest, most cramped tube and out the shaft of the penis before they even get to the vagina. Once they hit the battleground, the vagina tries to kill them with acid. If they survive that, cells in the vagina start eating them alive. If they make it past the vagina, the cervix squirts out this sedcutive little river to make it easier for them to swim through, sort of like a little temptress who's luring them deeper into a trap. Most of them get disoriented and just ram against the wall and die. Those who make it through, they have to swim UPSTREAM through the fallopian tubes. There are little cilia in the fallopian tubes that actually create a current that makes their mission even more impossible. And then, even after they swim all that way and if they don't die before they make it to the ovary, then they might realize, oh crap, this is the wrong freaking ovary! There's no egg here!

So millions of sperm set out to find the egg and usually only about 50 make it. Which means, as Mack pointed out, we start out the best of the best and it's all downhill from there.

Also, do you know why the U.S. isn't on the metric system? Would it suprise you to know that Thomas Jefferson tried to adopt the metric system back when he was president? Would it suprise you even more to know that his secretary of the treasury, Alexander Hamilton, tried to acclimate people to the metric system by switching our money from shillings and pounds to dollars and cents? Would you be floored that I now know that's why Hamilton is on the $10 bill? And since they redid the money recently, Hamilton is looking like one sexy metric system supporter.
