18 myths everyone believes that are actually false

For as long as time has existed, there have been myths and legends. We love to talk about interesting facts but sometimes, things can get a bit jumbled along the way.

Much like a game of Chinese whispers, it seems that some things we’ve believed all of our lives could be the opposite, or not true at all.

Here’s 18 myths that have actually been debunked!

2. A goldfish has a memory of only 3 seconds

Strange, but not true. A team actually trained a goldfish to remember an obstacle course a month after it had last swam through it. Other fish studies have shown fish have normal memories – so don’t forget to feed yours!

3. Leave the light on instead of turning it off – it’ll save electricity

The team on popular show MythBusters have debunked this common myth. They calculated that the power surge from turning on a light would only consume as much power as leaving it on for a fraction of a second. Also, the wear and tear of turning a light on and off repeatedly did not reduce the bulb’s total life expectancy enough to offset the increased electricity usage. So…it is better turn a light off rather than leaving it on.

 

4. A cereal box has more nutritional value than the food inside it

While there’s a lot of sugar and other bad stuff in cereals these days, they do hold at least a little nutritional value. As for cardboard, is has no nutritional value AND it has toxic chemicals.

10. Shaving thickens hair

This seems like a myth that was perpetuated by waxing companies, because it’s false. Shaving hair does not make it thicker, it just looks like it.

You might have heard that you shouldn’t wake a sleep walker but you can – they’ll be a bit disoriented but it’s worth it as they could harm themselves otherwise.

 

12. The five-second rule

If you drop food, you can eat it as long as it wasn’t on the floor for more than five seconds, right? Actually, no. Once the food hits the floor, it gets the germs immediately.

When we think of Vikings, we often think of horned helmets. But actually the 9th century Oseburg tapestry that myth is based on shows a God performing a ritual with the horned helmet, meaning they weren’t a Viking.

17. Cracking knuckles gives you arthritis

This is false – so crack away! It’s simply air bubbles releasing and does not present a risk.

 

18. Fingernails and hair keep growing after you die

Nope – once you die, everything in your body does too, even your hair and fingernails.
