What obvious adult discoveries made you feel a bit of a plonker?

What’s something you learnt as an adult that made you think that’s completely obvious and yet I have never considered that….i feel like a bit of a plonker?

Mine was when taking tablets, the more you drink with it the better it will dissolve. I think alot of tablets are testing with the assumption people will drink 250ml alongside it.

Not as an adult, but a teen in high school science/biology when I learnt how the digestive system worked. Until then I had been taught by mum that liquid went down one pipe and food down another and it was all processed separately until it came out the end separately. Amazingly, I went on to become a Dr🤣. Never corrected her either, she seemed so sure of it😆.

ETA - mum was definitely not up there with her medical knowledge in any other way, such as putting butter on burns, toothpaste on cuts and 101 other things that belong in a ‘wtf’ book. Upside was this prepared me for the many bizarre people that would cross my path in a medical capacity, nothing surprised me 🫤.

Edited

My mum loves vaseline-its her go to cure for most things.
Her other not quite so great cures,
Butter on burns
Whiskey in the fish tank if any fish looked a bit ill(she insisted it brought back many a goldfish)

Can you explain about the speed limiter, is that something different to cruise control?

Yes, it's different. In ny Dacia, the speed limiter button is on the right near the steering wheel, you press it, then select the speed you want (it starts at the speed you're currently at). The cruise control keeps the car at the speed you select until you brake and is very near the speed limiter selector

@Takethehuntingquiche @Thegirlwhowent maybe this would help?

That does help, thank you. I do indeed feel like a plonker now 🤣

I only realised last week that vitamins is short for vital minerals.

Also, in Harry Potter Diagon Alley is the word diagonally split into two words.

Didn’t know either of those. Thanks for sharing.

Vitamins is not short for vital minerals so you should forget that.

Harry literally says “diagonally” when he uses the floo powder, and the joke about him saying diagonally is in the film. It isn’t news.

I also use an electric brush and move it like I would a Manuel which I think creates more froth and spit

@TessTickle0 I used to do that as well until I was told by my dentist that, over a period of time, it damages the enamel on your teeth.

You just need to hold the brush on each tooth for a short while and let it do it's job.

Are chickens specifically female? I thought the females were hens, and the males were cocks.

Who knows the word for a male bee? Hint: the meaning most people are familiar with is a remote controlled aircraft.

I agree with you; you can use 'chickens' for either sex.

Correct, although nearly all chicks are female. The egg industry kills most males. This is being slowly phased out as the technologies for sexing undeveloped chicks in the egg become more readily available.

Good news, we say - but it's putting chicken sexers out of work! It's an actual skilled job. They can glance at a chick's bum and know if it's male or female. If you've ever examined a days-old chick up close, you'll understand what a near-magical ability this is 🐥

Yes, I can only tell once they start to grow and the males shoot up much more than the females.

Used to live in a London suburb with Korean neighbour family who were very skllled at that job.
