You know what would be really handy? If a trained rally driver with access to a bunch of all-wheel drive and four-wheel drive vehicles helpfully explained the difference between these two ever-more confused terms. Oh wait, here he is!

The ketogenic diet (or 'keto' for short) involves the eradication of most carbs from your diet in favour of proteins and fats. It has exploded in popularity among women in recent years, with multiple mummy blogs singing its virtues.

However, there's a slightly icky side-effect you may wish to ponder before embarking on a high-fat, low-carb diet. In short, it can cause a marked change in vaginal odour - AKA the 'Keto Crotch'.

Chronic wasting disease has now been reported in deer, elk, and moose in 24 states across the US, according to the CDC. The disease isn’t new, but its nickname is: you can now read sensational headlines about “zombie deer.”

Quick, think of things that are fast! Rockets? OK. Cheetahs? Sure, absolutely. Bullets? Oh, yes, quite. A bowl of rich, creamy soup? Ah, generally, no. Not so much. Then why do we call cars that have been made to go faster “souped-up?”

There’s an extremely common design trend that may have slipped by right under your nose, slowly taking over seemingly ever new car on the road, one by one. It’s only maybe a couple inches wide at most, and at all four corners of the car. It’s purpose a mystery, until now.

I’m not much of a cryer, but when I do, I bawl.

The English language was first spoken in early medieval England around 1400 years ago. This gradually gave rise to today's 'Modern English' which became the dominant form by the 1550s. Today I discovered some of the earliest English words that are still in common usage today.

Earlier this week, Google's CEO Sundar Pichai faced a House Judiciary Committee in the United States Congress to answer questions about recent data breaches and other important security matters. So, naturally, the discussion turned to extremely serious and important matters. Like why searches on Google for the word "idiot" turn up images of President Donald Trump.

In 1930, a wild, black-haired, green-eyed tomboy commanding her motorcycle caught the eye of a man named Tommy Wisdom. He was working as a journalist at a motorsport magazine and knew that this beautiful woman was going to be his partner in life.

Two blowflies were chowing down on a dog turd mixed with their own vomit for lunch. One of the flies burped. The other replied: "Don't be so disgusting while I'm eating!"

But anyway.

What's inside the glowing briefcase in Pulp Fiction? It's one of the greatest mysteries in cinema. Quentin Tarantino has remained deliberately coy on the subject, vowing to never reveal the answer. "It's whatever the viewer wants it to be," he once teased.

Except that's not quite true. The answer is explicitly spelled out in an original screenplay draft. (Spoiler: It has nothing to do with Marsellus Wallace's soul.)

Have you ever wondered why we call Frankfurt sausage rolls "hot dogs"? When you stop and think about it, that's a pretty disgusting name for a Western dish. As it turns out, the origin of the word is fittingly repellent - and it means exactly what you think.

If Porsche were a person, it would be the student with the unique name in a class full of Davids and Brittanys. “Porsch?” the substitute teacher questions, every time, after smoothly going down the list otherwise. “Porsch? P—ortch?”

One of the unintended benefits of virtual-reality headsets is the ability to watch TV. The Google Daydream, Samsung Galaxy Gear VR and PlayStation VR are provide excellent private viewing theatres to catch up on your favourite shows.

Today I discovered that this concept isn't new. In 1937, a British company launched a tiny, personalised TV set known as the 'Television Monocle'. Tell me you don't want one.

Graphic designers, you should probably stay away from this one. This optical illusion messes with your vision in a way that creates false colours that could linger for over three months - though don't worry, you have to be trying pretty hard to have that pronounced an effect. It's called the McCollough effect, and here is how it works.

It feels kind of incongruous to think of Nazis celebrating Christmas, but adapting the yearly holiday was apparently a key part of the new way of life Hitler and his followers were trying to build. In an attempt to rid Christmas of any Jewish implications, however, it was reinvented with a more Germanic pagan vibe.

In 2017, Bitcoin's value soared from $1200 to around $25,000 before dropping down to around $16,000 at the end of the year. Since then, it's value has risen and dropped sporadically from day to day, dragging smaller cryptocurrencies such as Ether and Ripple along with it.

Everybody loves a cheeky chicken McNugget now and again. Perhaps, even, multiple McNuggets. Today I learnt that, for all the McNuggets I've ever eaten in my life, McDonald's only produces nuggets in four different shapes: The Bell, The Bow-Tie, The Boot and The Ball.

Mind. Blown.

The Second World War swallowed up the years between 1939 and 1945, affecting people across the globe and ending as the deadliest conflict in human history. As some of humanity's darkest days, it's origins and legacy are taught in schools across the world. It may be easy to understand who attacked who - but it isn't easy to fully comprehend the scale until it's laid out for you in simple, easy to understand terms.

Just like this two-part video series does.
