Sometimes, life presents us with unbearable dilemmas—like when you drop your last cookie on the kitchen floor. Do you quickly pick it up and eat it? Does eating a cookie off the floor make you a savage? When you drop a piece of food on the ground, how much time do you really have before it becomes contaminated?

Kinda lame he didn't just hand them a cookie after, especially to the guy who ate the floor cookie. I mean he had a full plate of them, is he gonna eat all of grammy's cookies?

I honestly use the 5 second rule as an excuse to eat food that someone dropped on the floor. I don't care if food is on the floor, as long as it's fine, I'll eat it.

We live in a bed thats full of shit. (housedust allergy is basically you having an allergy to mites shit). when you flush your toilet small particles get into the air and basically your bowl is cleaner then your toothbrush because these particles get into the air. infact: your fridge-wall or a smartphone screen has more bacteria than your toilet seat on it. we evolved to eat raw plants directly from harvesting and our ancestors just like animals today draged the hunted pray miles through the dirt to eat it from the dirt. and people complain about food that touched the floor for 3 seconds that is cleaned every week or so. evolution made us pussies

To me; if my food drops on the floor for more than 10 seconds i wouldnt give a shit and just eat it still, unless i drop it in dirty substances like water or soil and stuff like that.

for people who wouldnt eat the cookie, you have the same germs on your hands and the inside of your mouth. Thats why we have immune systems. If you dont eat food off the floor, you shouldnt eat food off your hands or your tongue

'Invaderguy78' 2 years ago
I'm still not gonna eat it, what if the bacteria multiplies as I eat and digest it. If it survives anti bacterial stuff, then it's a threat.

why does he measure a germa speed in miles? wtf
'BromanderInChief' 2 years ago
I actually researched this for a science project years ago and to summarize what I found... Dry foods can be fine for anywhere from 30 seconds to slightly over a minute, depending on the size of the food. It seems that it was a parabola effect with size, with smaller dry foods like animal crackers and bigger dry foods like a circus lollipop having less time to pick up, and medium sized dry foods like cookies, certain candy bars and Jacked Doritos having the longest time threshold. However, you can still run the risk of having terrible luck and having the food land right on certain detrimental bacteria. So the 5 second rule in cases like this would work better than a 45 second rule, for example. WET FOODS ARE ALMOST IMMEDIATELY INFESTED. Unless you're a badass ninja with god tier reflexes, don't even bother.
