We've been waiting for weeks to eat that piece of pizza we dropped on the floor, and now we finally can because our good friend science has confirmed that the five-second rule is actually a beautiful reality. Which made us wonder … what other truths has science been keeping from us?

Finally. We've been waiting for weeks to eat that piece of pizza we dropped on the floor, and now we finally can because our good friend science has confirmed that the five-second rule is actually a beautiful reality.

In case you didn't know, the five-second rule is the once-mythical belief that food dropped on the floor is still edible if you pick it up before five seconds pass. But, a study just confirmed that there is almost no bacterial transfer to food within five seconds of it hitting the floor.

According to the study, time is a significant factor in bacterial transfer from the floor to a piece of food, but the type of floor you drop it on also matters. Carpet, apparently, is the safest place to drop your filet mignon before picking it up and shoving it your face, while laminate surfaces are the least safe. The longer you leave it there, the more fucked you are, but it also largely depends on the type of bacteria that are present on the floor at the time of your clumsy dropping.

The team also did a survey on the number of people who used the 5-second rule. It found that 87 percent of people surveyed said they would eat food dropped on the floor, or already have done so. We are not alone.

But all this myth-busting made us hungry for more myth-busting, so we found you some more myths that are actually true to satisfy your thirst for truth:

1. Animals know when danger is coming

And no, we don't mean that puppy parka you keep trying to dress them up in. We're talking about the fact that those little buggers are capable of hearing extremely low-frequency sounds and sensing seismic vibrations from earthquakes that haven't hit yet. That's why they all run for higher ground before an earthquake or tsunami, while you stand there and scratch your head like a doofus.

2. When you 'sleep on it,' you make better decisions

Getting a good night's sleep before making a major decision actually improves our capacity to make the most optimal choice. One study found that people who sleep better the night before a huge choice made the right one most of the time, while people who stayed up all night watching Big Booty Hoes Volume 14 made shitty decisions that negatively affected them. So go to bed.

3. Chicken soup literally cures you

"Don't drink chicken soup when you're sick," said no one ever. Rather, chicken soup should be consumed in delicious mass quantities if you've come down with a bad case of bird flu or pneumonia. That's because chicken soup slows down the making of mucus and makes it drain out more efficiently. Mucus, dear friends, contains all the bacteria that are making you sick, so guzzle chicken soup as one would guzzle tequila off a stripper's tits.

4. You can predict the weather through joint pain

When your grandma whines about it being about to rain, then clenches her knees, it's not her moving into a more advanced stage of dementia. She's predicting the weather, because she's magical. Some people are capable of sensing changes in barometric pressure that signal rain in their joints, especially people with arthritis or past injuries. The rest of you can just check your phone app like the lazy bastards you are.

5. Celery contains negative calories

Celery is made of practically nothing, so you actually burn more energy by eating it than it provides to you in nutrition. But, there's still some cellulose and fiber in it which makes you feel full. So you're basically eating without eating. Why can't burgers do that?

6. Aged sexpert Dr. Ruth was a sniper in Israel

Yep. She killed civilians and our sex drive.
