Seems that I am NEVER tired of this motherfucking sloth on this motherfucking boat!

The sloth equivalent of the ending of 2001


John Holmes Motherfucker - 2013-02-21

Thinking about whether a video of "the sloth equivalent of the ending of 2001" would worth attempting.


James Woods - 2013-02-21

Yes, John, it would.


John Holmes Motherfucker - 2013-02-22

OH hell yes.

This is some Herzog shit.

I never know what to do with my hands either, sloth


Father Avalanche - 2013-02-21

I choked on my beverage because of you.

I'm so glad sloths don't explode at high speed. What a happy video.


Chalkdust - 2013-02-21

what an odd thing to be concerned about

Well, they say that the physics of a giraffe are incredibly complex. You know how if you lay down for a while and then get up you're light headed? That's a phenomenon called orthostatic hypotension. Our hearts transport blood at a pressure that can perfuse brain tissue as well as every capillary in our body, which involves overcoming a lot of resistance. When we stand up quickly, the pressure doesn't adjust quickly enough sometimes so your brain is temporarily malnourished for blood. This is also why fainting people regain consciousness when they hit the ground, because the heart doesn't need to work that hard to overcome gravity and resistance nearly as much.
Now imagine a giraffe. Their necks stretch out 6 feet or more. If you've taken a basic physics class, you know how much hydrostatic pressure is needed to pump fluid to heights, so you know that their blood pressure must be very high (over twice ours in fact, and in a much greater volume) to reach their brains on the other side of that long neck and several meters from the heart.
And yet the weirdest thing is that while we get dizzy when our hearts make that tiny change from prostrate to standing, giraffes can go from having their heads fully upright (at tree level!) to level with their heart in mere seconds. It's not impressive till you really look at the forces involved. Thankfully, they have a rete mirabile in their neck that prevents their brains from exploding every time they bend to take a drink.

So, in a very strange way, I think nature has fascinating and strange forces in it. I think sometimes animals are adapted in really specific ways to maintain these powerful internal forces. When I say exploding sloth, I merely say that if something is adapted for millions of years hanging out in trees, I wouldn't be surprised if great speeds would hurt it in some way. Yes, I know there were people worried about the steam engine too, saying humans wouldn't possibly be able to survive at such unnatural speeds! And no, I wouldn't ever think a sloth would actually be harmed at high speeds, just saying... what a wonderful and crazy thing nature is.

Take some stars. You earned them.

That was supposed to be a reply to Jet Bin Fever but this works too.

I barely remember typing it. I had just gotten off a twelve hour shift. I think I passed out soon after.
