If it folds up to fit under your bed, it's a revolution.

Do you know what scientists have discovered about the human body?

Nothing.

They have no idea, and it's time we accepted that. I mean sure, they've got some general things figured out:

You should probably eat something other than candy bars.
You should get up and go outside once in a while.
That water stuff? It seems kinda important.
And if you have time, maybe sleep once in a while.

But beyond those things I have trouble believing that the vast spectrum of human diversity can be summed up by a "recent medical study." How many people were in the study? One-hundred? That's 1/60,000,000th of the humanity, not what you'd call a good sample.

I used to enjoy debating vocal pro-Earth advocates (read: "Playing devil's-advocate to people I found obnoxious.") because I got to lay out this argument:

"I'm not saying that global warming isn't real, just that the people who tell us about it also depend on it for their grant money. If it weren't for global warming, who would care about climatology? No one. So then how can we trust a climatologist's opinion on the subject? It's like if a man who owned a chocolate factory told you that eating chocolate made you live longer, would you believe him? No."

But I had to stop using that bit when medical studies found that dark chocolate* contains antioxidants, which prevent cancer and thus MAKE YOU LIVE LONGER. That's right, even my candy bar rule is coming into question now.

But medical studies aren't nearly as good as the home fitness industry. I'm convinced that all those late-night workout machine commercials are created by executives trying to see who can make people do the stupidest thing:

"I'll bet I can sell a machine with a bow on it, like from a bow and arrow. I'll say it has 'Thrust-bar resistance' or something."
"Oh that's nothing, I bet I can make people pretend to ski in their living rooms."
"Ok, fine. You know push-ups? Did you know you've been doing them wrong all this time? No? Well that's because I just decided it."

Meanwhile, in homes across the country . . .

"Of course, skiing! That's it! All this time I've been so unhealthy, and it was so simple! Now I can be fit and never leave my house!"

That's right, even my "go outside" rule is coming into question now.

So here it is, the entirety of what we know about the human body: Drink water. Sleep.

That's it. Good luck folks.

*You notice they didn't try to say this about chocolate in general, because no one would buy that. But DARK chocolate? Well that's different! It's magic!
