5 Science Myths That You Still Think Are True But Are So Wrong You Will Hate Yourself

Our lives have gotten to the point that probably ninety per cent of the things we believe to be true are actually what we've heard by word-of-mouth: things your friends say that sound like they could be true,  you never get around to googling them, and then end up telling  others at a party a few days later. Yeah. Most of those things are probably not true.

1) The Five Second Rule

You dropped that open-faced sandwiched face-up (finally!), you're heartbroken, and you pull out the five-second rule. Let's be real: the floor's got grime on it, it's going to rub onto your food, dusty dirt and food particles are going to mingle. Let go.

2) Forensic Science works like on CSI

Let's not even get into the fact that DNA analyses take weeks and months to complete. Let's talk about the DNA samples that seem to get every criminal caught because of that one stray piece of dead skin or whatever they left on the crime scene. What about all the other fucking millions of DNA samples that you pick up on the daily: being jostled by people on city streets, taking cabs, at bars/restaurants--you know, just daily life with other humans. You pick up tiny pieces of DNA everywhere, and its not that easy to find, analyze, and track back. Horatio Caine badassery just doesn't happen in real life.

3) Fat cells don't die

You know the saying "brain cells come and go, but fat cells live forever"? Well, it's kind of misleading bullshit. Every year, 10% of your body's fat cells die, and are replaced by newer ones. On that note, if you kill a bunch of brain cells when you're younger, they actual can be replaced by newer ones when you're older.

4) Lightning doesn't strike twice

It does. It hit the empire state building thrice this one time.

5) The tongue-rolling gene:

I've believed for ages that if you can't roll your tongue lengthwise, you just lack the gene that allows you to do it. It made the round of the internet a while ago. Apparently, though, studies show that you can in fact learn the skill, as impossible as it may seem, so there's no way that it's entirely a genetically inherited skill. Just don't try to learn it in public, you look like an idiot.

Well, then. I'm going to attempt to roll my tongue now.
