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.

No, relax, the little piggy really did go to the market to shop. I remember the Ladybird book illustration, she had a basket with her.

Pretty sure they didn't carry aquatic animals on the Ark during the flood of a lot more water. Also, the other animals in their twos were then meant to disembark and procreate, rather than jyst die next to the Ark. In reality, they 'd have probably just eaten each other, and you'd just be left with a couple of apex predators.

My car has adjustable seat belt heights. It's still not low enough to really stop the risk of me decapitating myself, though it's a little better. I'm a very average woman's height of 5'4".

Coming up to Christmas every year, Mum always used to buy a tongue, boil it, peel the outer skin off (that was our job once we were older,) then press it into an old biscuit tin (those round Danish butter biscuits ones) and place a very heavy weight on the lid to so it would set in a round shape, rather than uncurling. I am not that keen on tongue, because of the taste - its preparation doesn't bother me, though. But Dad always thought it a great treat.

I was an adult when I found out narwhals are real and not a mythical creature in the same category as fairies, mermaids and unicorns 😂

I thought there was a small animal called a haggis that was native to Scotland.

Gherkins are not small cucumbers!

Guess you are learning something new today..... same plant species. Even Aldi packaging says mini cucumbers

That yellow dandelions and fluffy dandelions are the same dandelion, not different varieties.

I am intelligent, educated woman with a long interest in gardening yet I've reached the grand age of 36 before learning this.

That, despite a comprehensive education, women don’t piss out of their vaginas. And yes I am a woman.

I think that episode in Orange is the new black was a learning curve for many females!

EBearhug · 21/09/2026 21:28

They're all cucumbers. They're different varieties of cucumbers. Like you cantaloupe and hineydew and water melons. Plus melon and cucumbers and courgettes are all the same family, cucurbitae.

I read an article recently about there being loads of varieties of common dandelion - o'r do you mean the seedheads?

My granny once presented us with a whole cow’s tongue on a platter. With mashed potatoes. It was delicious as long as I didn’t look at it or think about it too much.

Tongue is a good bit of meat.

Of course it’s easy to get squeamish working with a whole ox tongue and thinking about your own tongue, but that’s when we laugh at ourselves.

I've posted this before but I thought the channel tunnel was under the sea not under the sea bed.

Sorry, it’s UNDER THE SEA BED?!?!?

I didn't know until long after I'd birthed three babies (two of whom are female) that baby girls are born with all their egg cells already.

Blew my mind that my daughter's eggs were made in my body. Literally never gave it a moment's thought prior to learning that fact.

My father used to heat tins of rice pudding or soup or any food tins by putting said tins in a pan of water and then "boiling them until the label falls off" which indicated that they were done/cooked. This was presented to me as a bono fide known alternative to opening the tin and heating the contents in a pan. Keeps the flavour in and there's less washing up!

I never realised how odd this was until I was at university and asking my friend which method they were going to use to heat some rice pudding or soup or whatever. They looked at me like I was nuts and I remember picking up the tin to look at the instructions expecting to see both "methods" listed.

I was really surprised to learn this was something my Dad had devised rather than an accepted way to heat tinned food 😂

Did your dad ever serve? The old ration packs, I still remember my dad coming home with them, were in gold tins which they did indeed boil in the can! Even the chocolate and boiled sweets came in a can,. Used to love them!

I was well into my 30s, maybe, before I realised West Berlin was surrounded by East Germany. How emasculating for the DDR to have half of one of your major city belonging to another country.

I learned this within the last month. I'm 51 years old 😳

A huge number of women and girls do. Don’t shame people for that, you’re being awful. Just make sure any girls in your life know how it all actually works.

Well said

You get great salad. Slice it finely, either in round o'r ribbons, dress with white wine vinegar, sprinkle with chopped chives.

Actually maybe people can tell me - why do they tip their head back to swallow tablets? They don't do it with anything else they swallow.

I remember seeing a lecture by someone on, amongst other things, how swallowing works and he demonstrated the fact that gravity has nothing to do with it by standing on his head and drinking water.

I do it because I don't want any of the tablet to start to dissolve on my tongue & hit my taste buds. Paracetamol is very bitter - other tablets also taste foul to me.

I was playing golf one clear summer day with another middle aged woman when I commented how lovely the moon looked in the perfect blue sky. She was totally amazed that the moon could be visible during the day and had never noticed it before!

That cous cous isn't a grain, it's a type of pasta.

So why do supermarkets always shelve it with the grains and pulses?!

Pssst to all MN. Check your cupboards and hide the orzo. @PieLittlePony has had enough shocks for one day.😱

Not me, but I was shocked some years ago to find that dh, who has a degree and prof. qualifications, and attended a very academic boys’ school, had never heard of photosynthesis. The whole process on which life on earth depends, was completely new to him.

That’s amazing!

Minasama · 21/09/2026 22:19

That your child was once in your mother’s body (as an egg in your ovary when you were a baby in her tummy.) This blows my mind. I didn’t even know we were born with all our eggs.

Also I only discovered a couple of months ago that MDMA is ecstasy and that some types of vapes are illegal, both of these things unfortunately from the head teacher of my daughter’s school due to her behaviour…
