In the movie, Jerry Maguire, Dorothy Boyd's (Renee Zellweger) son, Ray, engaged Jerry in a fact duel.
He asked, "Did you know that the human head weighs eight pounds?"
I didn't know that. In fact, I had to look it up because it bugged me to think that my entire existence, everything I've learned, experienced, essentially everything I am is encased in a skin and bone structure that sits on top of my neck and it only weighs eight pounds. Seems smallish to me.
Of course the kid didn't say that eight pounds was the average, or whether he was referring to adult noggins or kid sized craniums. And what about smart people? Do their heads weigh more by virtue of the extra knowledge they lug around with them? Conversely, are stupid people's top knots less hefty than the average person's?
Turns out Ray was close, the average adult human head weighs about ten pounds. It still seems small to me, but I can't argue with facts.
Here's another fact about the head, well..., the brain inside it anyway. Our brain is about 2% of our body mass, but draws about 20% of the energy our bodies use. Again, the amount just doesn't seem to be enough. I think a lot and when I think about things like The Zombie Apocalypse, flan, or why my daughter insisted on dressing my grandson up as a lemur for Halloween, I'm sure I'm using way more than 20% of the energy my body is expending at that moment. 30% at least.
Cold, hard facts are hard to argue. For instance, it's hard to argue about the number two. It's a fact, 2 is two and there's nothing much more you can say about it. If you say that two isn't two, but something less you'd be right because two wouldn't be two if it were something less than two. The opposite is true as well, so what's there to argue about? Makes my grey matter heat up just writing about it, which, again, is a fact. ( I suppose you could say that something more than two is two, but what sense would that make unless you just want to argue, which is OK by me, too. I don't judge.)
If you are into facts then you've come to the right place. In this week's Free on iTunes I'm looking at three (3!) fact apps. So let's get to the facts.
There are other surprisingly interesting facts about our bodies beyond the average size of the adult human cranium. For instance, your kidneys process about 400 gallons of blood each day. Did you know that your brain starts to shrink after you reach 30 years old? (That explains A LOT!!!)
Human Body Facts 1000
Those facts and 998 more await you in Human Body Facts 1000. This is a simple app (likely made so for those of us well passed 30) with just a place to display the fact, some basic controls for going to the next or previous fact, and a way to add and show all your favorite facts.
Though it's basic, and ad supported, it's still worthy of a download if for no other reason than to learn how many arteries the human hand contains. You're dying to know, right?
Weird Fun Facts
If you'd like to stuff your grey matters with a wider variety of facts then Weird Fun Facts may be just what you need.
Peaches were once known as Persian Apples. Rain contains vitamin B12 ( I knew I liked getting caught in the rain and pinã coladas for some reason.) Cats don't meow to other cats, just to humans.
Weird Fun Facts
Interesting, right? Again, the interface is simple. Facts appear in the center of the screen. You swipe left or right to see more facts. This app will let you search for facts and have them listed by category. If you like a fact you can give it a thumbs up and doing so will reveal how many other users agree with you.
Weird Fun Facts is ad supported, but that doesn't make it bad. Grab it and see what you think.
20000+ Random Facts
If 1000 facts about the human body aren't enough for you, and weird fun facts could be weirder and...umm...more fun, then what you need is more facts. 20000 more to be precise. While we're at it lets randomize those facts to make it so you'll never know which fact you'll discover at any given time. Now you have a good idea what 20000+ Random Facts is all about.
One of 20000+ Random Facts
Again, the interface is simple and ad supported. You page through fact after random fact. If you like a particular fact you can "like" it with the heart icon. Other features include the ability to send a fact to a friend (or enemy) via email and a random chat feature where you can strike up a conversation with a complete (= axe murderer) stranger.
20000+ Random Facts does have some unique facts in its database. What all of these apps need is a link to where you can find more information about the supposed fact. At least a reference listing. I mean, how do I know for sure that 1.5 million Americans are charged with drunk driving each year? Once again, the number sounds really low to me.
Anyway, if you're interested in 20000+ dubious facts 20000+ Random Facts can deliver.
And that's a wrap for this week. More freebies next week.
